- Word of God confirms that Dumbledore was in love with his friend-turned-genocidal-maniac Grindelwald, hence his reticence in defeating him, and his lack of romantic relationships in later life.
- Remus Lupin and Sirius Black.
"Together?""I think so."
- In the third book, Remus is very quick to believe Sirius' innocence — even though the truth just transfers the responsibility for multiple murders and Lily and James' betrayal and subsequent deaths from one former friend to another, he abandons suspicion for Sirius almost immediately and hugs him instead.
- Similarly, the controlled, stoic Remus is noticeably touchy on the subject of Sirius, and clearly doesn't want him to receive the Dementor's Kiss... which isn't so strange, until you compare his later willingness to hand Peter over to the Dementors, or straight-up murder him (in front of three children, no less) for the same crimes. Even with the Dementor's Kiss viewed as a Fate Worse than Death, there's a dissonance here.
- Twice in the Shrieking Shack scene they exchange the same words:
- Remus looks at Sirius, a lot.
- Sirius and Lupin are known to have lived together from the end of Goblet of Fire until the end of the Order of the Phoenix, and give Harry a shared Christmas present (generally something done by couples).
- Lupin only got with Tonks after Sirius died. The pair are barely seen interacting, let alone developing a relationship.
- One example: towards the beginning of the film version of Order of the Phoenix, in the first scene in 12 Grimmauld Place, there's a shot where Sirius just so happens to be sitting in front of a map, which Lupin just so happens to be reading over the top of Sirius's head. The result is a little like spooning.
- The film version of Harry Potter and the Prisoner of Azkaban adds even more romantic undertones to their relationship. For instance, Snape makes fun of them for "quarreling like an old married couple". And then there's the Cooldown Hug complete with very emotional monologue that Sirius tries to use to stop Remus's werewolf transformation.
- Harry and Ron. Their fight in the Goblet of Fire resembled a lovers' spat.
- The Soup completely backs you up on this.
- Previously in Chamber of Secrets: "...[Harry] contended himself with scrawling a note to Ron: Let's do it tonight. Ron read the message, swallowed hard, and looked sideways at the empty seat usually filled by Hermione. The sight seemed to stiffen his resolve, and he nodded."
- Goblet of Fire also gave us the chapter where the Triwizard contestants had to rescue "the thing they would miss the most" from the bottom of the lake. For Harry, it's Ron. Dobby goes all Shipper on Deck by demanding Harry rescue "his Wheezy."
- It was even more explicit in the Malay translation of Goblet of Fire, where it was translated as "the contestants have to rescue the thing they love the most".
- Harry asking Ron to go away with him before the wedding in TDH part one.
- Later on, Ron pulling a shirtless Harry from the lake before their Crowning Moment of Heartwarming.
- Ron helps Harry get dressed after he breaks his arm in Chamber of Secrets. Granted, they're twelve in this book, and there was nothing about getting undressed.
- During the Yule Ball in Goblet of Fire, Harry and Ron go out into the grounds to see several bushes being used by couples as a Make-Out Point. They themselves then hide in the bushes so Hagrid doesn't overhear him talking to Madame Maxime about their shared giant heritage. After Hagrid and Maxime leave, Snape comes along reprimanding the students kissing in the bushes, he then comes across Harry and Ron and looks very confused.
- Ron spends most nights in Order of the Phoenix taking care of Harry — watching over him, waking him up when he's screaming from nightmarish visions, talking to him and calming him down afterwards...
- Harry and Tom Riddle: Though technically third-person, the series is essentially presented from Harry's viewpoint. So it can be argued that the narration describing the... positive physical attributes... of Tom Riddle (whom the narrative calls "handsome" seven times) seems to cause this.
- Harry and Cedric's interactions in book four (mostly construed as them just being good sports, but people use it).
- When Dudley says to Harry "Who's Cedric, your boyfriend?", Harry doesn't actually deny it... and Dudley only knows about Cedric because Harry was saying his name in his sleep (of course that could just be that on/off PTSD of his...).
- When Krum first showed up at Hogwarts, Ron gets jealous that Malfoy gets to speak to him before Ron can. He even said he wanted Viktor to sleep in his room.
"We could offer him a space in our dormitory, Harry ... I wouldn't mind giving him my bed, I could kip on a camp-bed."
- The movie takes it a humorous step further in one scene, wherein Ron is gushing over how awesome Krum is. Ginny walks by and jokingly comments "you're in love, Ron."
- In the chapter The Unbreakable Vow in HBP, the Malay version states that Harry is surprised to hear Draco talking rudely to Professor Snape, who is usually 'dihormatinya malah disayangi', which literally translates to 'respected, even loved by him'.
- Colin Creevey's fanboy crush on Harry.
- Harry's massive crush on the Half-Blood Prince
Ron: Yeah you do. You read a chapter every day before you go to bed - all you do is read that bloody book!
- That's not counting Ron sounding jealous.
- And the fact that Harry's boy-crush is, by extension, on Snape, as he is the "Half-blood Prince".
- James and Lily's Patronuses were a stag and doe. So this must mean that two people with those Patronuses are romantically compatible... wait a minute.
- This hasn't gone unnoticed, as there's quite a bit of fanart showing Snape and Harry reacting to the... interactions between their Patronuses.
- Barty Crouch Jr. definitely seems to idolise Voldemort a bit too much. It's taken to the extreme in the film adaptation of Goblet of Fire when he actually wipes blood off Harry's arm saying that his blood now runs within the Dark Lord, before licking it off his finger.
- Voldemort and Draco's bizarre hug in The Deathly Hallows Part Two.
- Snape's desire to look into Harry's eyes is suggestive, as this comic illustrates. Canonically, it's because Harry inherited those eyes from Lily, the only person Snape truly loved.
- It was probably unintentional but Snape's actions on Order of Phoenix stand out. The way he holds Harry's hand and forcefully takes him to the dungeon, and after that delivers the line "In this lessons, I'll attempt to penetrate, and you will attempt to resist." Out of context, it's even worse.
- Lupin acts unfalteringly cheerful toward Snape no matter how negatively Snape responds to his presence in The Prisoner of Azkaban, it's clear he was trying to make amends for their school days but it is constant. On the other side, Snape does try to kill a Death Eater who was aiming at Lupin.
- Ginny Weasley is all but stated to have been Luna Lovegood's only friend at Hogwarts for years. And during the DA meeting in Deathly Hallows, the pair of them share an armchair.
- Neville and Harry with Neville doing a Security Cling to Harry in book one.
- In Harry Potter and the Cursed Child there's lots between Albus and Scorpius.
