History HoYay / HonkaiStarRail

** When Jing Yuan approaches Scalegorge Waterscape and sees Dan Heng, Yanqing and the Stellaron Hunters, he specifically turns away from Blade to see Dan Heng in his Imbibitor Lunae form and closes his eyes before addressing everyone.

* [[https://www.hoyolab.com/article/27352535 "Aventurine's Timeline"]] shows that almost all of Aventurine's posts have Dr. Ratio's likes.

* The two of them start off with a bit of FoeYayShipping from the "Final Victor" light cone from the version 2.0 highlights page, as the art shows Aventurine holding Dr. Ratio's gun at himself, and the attached lore has him daring Ratio to pull the trigger in a game of Russian roulette. The effect is further enhanced by the voiced version of the light cone, where Aventurine sounds almost sultry as he proclaims himself the final victor. The tension only ramps up as Dr. Ratio accuses Aventurine of incompetence and threatens to report his failings to the IPC once the two are in Penacony.
* While Dr. Ratio is openly disdainful of Aventurine, as the story progresses it becomes obvious that despite their SnarkToSnarkCombat, Ratio does care about him, as [[spoiler:after the two's meeting with Sunday, he almost breaks character to make sure that Aventurine is all right, saying "just tell me if you can't hold on any longer". He gives Aventurine genuine advice on helping to find meaning in his struggles, and the owl shaped trinket he gives him as "doctor's prescription" is a genuine plea to come back alive, which touches Aventurine.]]
* On Aventurine's side, while outwardly, he eagerly participates in the duo's SnarkToSnarkCombat, his internal narration (as seen in the quest descriptions) shows that he genuinely respects the doctor's intellect and cleverness, even if he finds his know-it-all attitude amusing. He's also distraught at the thought that Ratio doesn't trust him and [[spoiler:may have betrayed him for real, even if it's just his paranoia talking]].
* A special mention goes to the moment where Aventurine finds himself shrunk in Dewlight Pavillion's sandpit and, upon seeing the giant (to him) Ratio, exclaims "[[DoubleEntendre Doctor, you're huge!]]" There is also an interactible spot on a viewing gallery in the sandpit where Aventurine can admire the view - the view being largely comprised of Ratio's chest - and the dialogue between the two where Aventurine notes that Ratio could squish him with a pinch in his current state, to which Ratio replies that he'd be happy to do so if Aventurine wants him to.
* Out of the game, the "Keeping Up with Star Rail" for Aventurine has Dr. Ratio as Owlbert's guest and being referred to as his friend, which he quickly denies and tells Owlbert that Aventurine is just more tolerable to work with. He then spends the entire runtime of the video alternating between berating Aventurine's strategies as unreliable, and [[{{Tsundere}} berating his opponents for thinking they can defeat Aventurine]]. By the end of the program, though, Owlbert tells him that Aventurine ''specifically requested'' him to be on the show and even has [[CrazyPrepared counter arguments prepared]] when a flustered Dr. Ratio quickly starts denying why he came on the program.
--->'''Owlbert''': I really can't tell what the deal is between you two.

** The "Aventurine's Timeline" on [[=HoYoLab=]] has Sunday liking Aventurine's magazine cover and the two like a social media post about a limited edition cologne that Aventurine buys out the entire stock.

* On Aventurine's side, while openly he eagerly participates in the duo's SnarkToSnarkCombat, his internal narration (as seen in the quest descriptions) shows that he genuinely respects the doctor's intellect and cleverness, even if he finds his know-it-all attitude amusing. He's also distraught at the thought that Ratio doesn't trust him and [[spoiler:may have betrayed him for real, even if it's just his paranoia talking]].

!!Specific Examples
* During the 1.4 "Jolted Awake From a Winter Dream" Special Program, after Topaz is introduced, she starts flirting with Himeko. Owlbert then snarks that they should get a room.
-->'''Topaz''': I also heard that the train's navigator was a lady of unparalleled beauty and talent.

* One of Argenti's voice lines describes Dan Heng as possessing a "unique form of beauty". If the two are added to a team, he tells Dan Heng that he feels honored to fight by his side.
* Topaz has a voice line calling Asta a "real lady" if she ever saw one and if the two are put on a team, she tells Asta they should hang out more. Asta has a voice line that indicates if their schedules have free time, they should take a vacation together to relax and share IPC gossip.
* Argenti and Velite in the "Night of Universal Hallucinations" quest. Argenti rescued Velite from being eaten in exchange for Velite swearing allegiance to Idrila, which he half-heartedly did out of self-preservation. In a conversation with the Trailblazer, Velite admits that while Argenti is quite handsome, he wonders if he can turn the knight into an IPC-sponsored idol. As the mission progresses, Velite does become concerned for Argenti, especially when Argenti's plan to fight the Giant Sting sounded like a suicide mission and because the knight did promise to take him home. While Argenti is ultimately successful in defeating the True Sting, he does text the Trailblazer that he found Velite again and apparently helped him re-ignite his abandoned dream of being a pilot.
-->'''Velite''': Don't die! I'll be waiting for you! After we fix this mess, you've got some spokesperson duties at my company to attend to! Just make sure you come back in one piece...
-->'''Argenti''': When I tracked down Velite, he said he saw himself flying, and steering the One and Only. I helped him to defeat the insect boss. However, he seemed a little lost after the illusion faded away.\\
'''Trailblazer''': I remember he said he wanted to be a pilot\\
'''Trailblazer''': And yet he says he has no obsessions and is immune to hallucinations\\
'''Trailblazer''': I suspect he was quietly affected by you...\\
'''Argenti''': He thought it over for a few days, but for some reason chose to give up this idea of using currency to spread Beauty... He seemed keen to become a pilot instead, and I showed him my support.

* In the "Long Wait for the Blade's Edge" mission, the Trailblazer can ask March for her opinion on the people they've met so far. When asked about Bronya, March replies that she finds Bronya pretty and likes looking at her.

* In the Aetherium Wars event mission in Cloudford, March and the Trailblazer meet Guinaifen and after introductions, Guinaifen comments that she finds March's name beautiful and makes sure she'll remember it.

* Aventurine and Dr. Ratio:

--->'''Owlbert''': I really can't tell what the deal is between you two.

* March is immediately starstruck when meeting Robin for the first time. And what does Robin say in response to this?
-->'''Robin''': I never thought a cutie like yourself would be a fan of mine

* In Acheron's [[https://www.hoyolab.com/article/26205872 character introduction, she mentions that she likes peaches]]. March's note is that Acheron can come on the Express and eat whatever she likes.
-->'''March 7th''': I've got lots of delicious snacks! Miss Acheron, you can come aboard the Express and take whatever you like~

** Siobhan also compliments March, who practically ''preens'' in response:
-->'''March 7th''': Did you hear that? She called me "my lovely lady"...!

** While Dr. Ratio is openly disdainful of Aventurine, as the story progresses it becomes obvious that despite their SnarkToSnarkCombat, Ratio does care about him, as [[spoiler:after the two's meeting with Sunday, he almost breaks character to make sure that Aventurine is all right and offer, saying "just tell me if you can't hold on any longer". He gives Aventurine genuine advice on helping to find meaning in his struggles, and the owl shaped trinket he gives him as "doctor's prescription" is a genuine plea to come back alive, which touches Aventurine.]]

** The tension further ramps up as Dr. Ratio accuses Aventurine of incompetence and threatens to report his failings to the IPC.
** Aventurine does call Dr. Ratio handsome and asks where his bust is while Dr. Ratio is openly disdainful of him. As the story progresses though, despite their SnarkToSnarkCombat, they do seem to care about each other as Dr. Ratio [[spoiler:gives Aventurine genuine advice on helping to find meaning in his struggles and the owl shaped trinket he gave to Aventurine is a genuine plea to come back alive, which touches Aventurine.]]
** The "Keeping Up with Star Rail" for Aventurine has Dr. Ratio as Owlbert's guest and being referred to as his friend, which he quickly denies and tells Owlbert that Aventurine is just more tolerable to work with.

* In the Reverie hotel lobby, Robin seems rather amused that Aventurine calls Sunday "the most handsome man in Penacony".

'''March 7th''': Oops, she's heard us...

* In the Cosmodyssey event, one of the Board encounters features the guests of the Reverie Hotel arguing about Blade's swordsmanship skills, in particular how fast his blade is. If you choose to join their discussion, you will get the highest amount of Trailblaze funds if you ask Dan Heng about the topic and he describes Blade's swordsmanship skills in detail, thus convincing all of the guests.

-->'''March 7th''': I've got lots of delicious snacks! Miss Acheron, you can come aboard the Express and take whatever you like~

** Aventurine does call Dr. Ratio handsome and asks where his bust is while Dr. Ratio is openly disdainful of him.

-->'''Black Swan''': My gaze has lingered on her for quite a while. Tonight, I initiate our first engagement. How about a dance?\\
'''Acheron''': Excuse me, are you asking me?

* The "Obsequies Performed, A Long Road Ahead" quest has Jing Yuan personally tell Dan Heng [[spoiler:that while his banishment edict has been lifted, there are still some people who are not happy about it, and he worries about Dan Heng's safety. During Dan Heng's companion quest, when he and Bailu are ambushed by assassins, Jing Yuan suddenly drops in and lends a helping hand, despite still recovering from the battle with Phantylia. It's implied that despite his injuries, he snuck out of the Alchemy Commission to follow them.]]
** There is also this optional dialogue at the end of the quest:

'''Acheron''': Excuse me, are you asking me?

* Just before 2.1, Hoyoverse released an animated short featuring Black Swan and Acheron intimately dancing with each other, with Black Swan remarking on how enchanting Acheron, calling her beautiful, and kissing her hand. About halfway through things take step toward [[FoeRomanceSubtext Foe Yay territory]] [[spoiler:once Black Swan confronts her about Duke Inferno's death.]]

* The 2.1 Special Program teased an animated short featuring Black Swan and Acheron intimately dancing with each other.

'''Acheron''': Excuse me, are you asking me?
** It's somehow even stronger in the full short, with Black Swan remarking on how enchanting Acheron is and calling her beautiful. About halfway through things take step toward [[FoeRomanceSubtext Foe Yay territory]] [[spoiler:once Black Swan confronts her about Duke Inferno's death.]]

'''Acheron''': Excuse me, are you asking me?

** The conversations they have before reuniting with the Astral Express seem to imply that the two were also very close in the past, and Jing Yuan still grapples with the loss. [[spoiler:At the end of the fight with Phantylia, Dan Heng is the one to catch Jing Yuan in his arms [[BridalCarry bridal-style]] as he falls and hovers over him as Phantylia leaves.]]
