General Tropes that apply for the duo:
It's difficult to talk about the main protagonists without talking about how they complement as much as they contrast the other. Given the nature of their relationship, however, some spoilers are likely to be unmarked.
- Adaptational Backstory Change: Their history together is consistently the same in every adaptation of the novel. However, the donghua adds one unique detail: the two met when they were children, but neither of them remember it.
- Age-Gap Romance: Played with. They're around the same age, but the body that Wei Wuxian was summoned into is a few years younger, which currently makes them technically qualify for this trope. There is also the fact that Wei Wuxian was dead for years, making his exact age ambiguous whether or not the years that passed while he was dead count.
- Amazingly Embarrassing Parents: Both of them love Lan Sizhui and make sure to treat him well with their best intentions in mind. But being the Sickeningly Sweethearts they are after they got together, it's inevitable that they can also be a handful to the young man whenever the latter has to cover up for them.
- Animal Motifs: Both of them are often represented by rabbits.
- Arc Words: From Wei Wuxian to Lan Wangji, "Look at me." Then from Lan Wangji to Wei Wuxian, "I'm here."
- Battle Couple: Whether they're solving a mystery or fighting someone, the two work well together as they're almost completely in sync with how the other thinks and acts.
- Belligerent Sexual Tension: Wei Wuxian and Lan Wangji start off their relationship with this, and it eventually turns into Unresolved Sexual Tension. Emphasis on the unresolved, at least for 90% of the novel.
- Colour-Coded for Your Convenience: In case one needs another way to tell them apart, Wei Wuxian is always seen wearing black and red clothes whereas Lan Wangji wears white and blue clothes.
- Elopement: After the whole mess with Jin Guangyao and Nie Mingjue has been dealt with, Wei Wuxian and Lan Wangji leave to elope, something Wei Wuxian even states word-for-word to Lan Sizhui. This serves as a Brick Joke, because Wei Wuxian said the exact same thing when he and Lan Wangji first set out to find the other pieces the demonic arm is a part of.
- Everyone Has Standards: Played for Laughs regarding their sex life. As kinky as they are and as much they're willing to try a lot of things, there are a few things that they are definitely not up for, such as making out in front of a child. And while they were initially curious about the idea of upside-down sex, the author revealed that after one try, they agreed to not do it again.
- First Love: What's even more profound is that they each other's first and only love.
- Foil: While deep down they're more similar than they initially appear to be, there's still a lot of things that sets them apart.
- Both are highly intelligent but contrast in how they behave in class; Wei Wuxian is the unorthodox and trouble-making rule-breaker whereas Lan Wangji is the perfect honor student.
- Both are good and selfless people but leave opposite impressions on other people and generally have different reputations. Wei Wuxian can be easily perceived as an evil and sadistic jerk with the slightest misstep, while many highly respect Lan Wangji and believe he can do no wrong. As lampshaded by Wei Wuxian himself in a situation where a noble thinks that Lan Wangji hasn't been taken yet, and this is after he and Wei Wuxian are already married:Wei Wuxian: You see, you're clearly not a virgin anymore, yet when people see your face, they say you are one no matter what. In my previous life, I've never touched a girl's hand except when I'm trying to save someone, but not a single person believed that I was a virgin. Night-hunting while at school! Everyone gossiped about me playing around with girls. Up on the Burial Mounds! Everyone gossiped about me being a satyr of anarchy.
- Both had a good relationship with their mother and loved their parents deeply, but Lan Wangji's parents had a checkered past whereas Wei Wuxian's parents have a clean slate; although the latter's parents are the subject of a few ugly rumors and insults.
- Good People Have Good Sex: After they got together, the two have been enjoying a healthy and active sex life. As Lan Wangji had put it, "Everyday means everyday."
- Happily Married: They elope shortly after the final arc and they are more than happy in their life as a married couple, now that they've resolved all their misunderstandings and are making up for lost time.
- High-School Sweethearts: Played with. They first met back when they were around fifteen or sixteen years old, but it would take years and several miscommunications and misunderstandings before they could even begin their "sweetheart" phase.
- Let's Wait a While: Defied. After the final arc, Wei Wuxian and Lan Wangji fully consummate their feelings. Wei Wuxian even lampshades how Lan Wangji might get in trouble for engaging in pre-marital sex, which is highly frowned upon in Chinese culture, but Lan Wangji doesn't care anymore.
- Living Emotional Crutch: A reconstruction of the trope. Over the course of the story, they had become this to the other without realizing it themselves. This doesn't mean they can't live without the other; they're completely capable of living on their own, but they had been deeply ingrained in each other's lives that they don't want a life without the other.
- Master of the Mixed Message: Both of them are guilty of this both in the past and present, which leads to one misunderstanding after another. In fact, if it weren't for the Big Bad and Lan Wangji's older brother, they would have remained oblivious to the other's feelings.
- Noble Male, Roguish Male: Wei Wuxian is the free-spirited and commoner-born Roguish Male, and Lan Wangji is the elegant and dignified Noble Male.
- Not So Different:
- Lan Sizhui makes a note that the two of them are actually more similar than they realize, taking on responsibilities and reliably seeing those responsibilities to the end. Even the author states that this is one of the main reasons why they fell for each other; they may be different on the outside, but they bond over their shared ideals and beliefs.
- In a less happy note, the two share a similar flaw. Both men tend to bottle up their feelings and frustrations which leads to the two talking past each other or outright not communicating. It takes a third party explaining the situation for the two to get together.
- Official Couple Ordeal Syndrome: While the two are already guaranteed to get together, what drives part of the plot is how, and more importantly, when that happens.
- Opposites Attract:
- Wei Wuxian's the Motor Mouth to Lan Wangji's The Quiet One, as well as The Villain opposed to Lan Wangji's The Hero.
- This trope more or less characterizes their entire relationship, except that where it truly matters, the two of them stand firm on protecting the things they hold dear. Circumstances in fact play a large part in making them the Star-Crossed Lovers that they would have been prior to Wei Wuxian's First Episode Resurrection.
- Red Oni, Blue Oni: Wei Wuxian easily comes across as the Red Oni while Lan Wangji is the Blue Oni.
- Sickeningly Sweethearts: What Wei Wuxian and Lan Wangji become after their Unresolved Sexual Tension finally gets resolved. Case in point, in the final arc, they're either physically glued together or not-so-subtly flirting with each other while they're confronting the Big Bad.
- Sword and Sorcerer: While both are proficient in both combat and cultivation, in the present time Wei Wuxian serves mainly as the Sorceror while Lan Wangji acts as the Sword.
- Their First Time: They get into some intimate caressing in Chapter 95, but they don't go all the way until Chapter 111, where they properly make love for the first time.
- Unrequited Love Switcheroo: Played with. Throughout the entire story, Wei Wuxian and Lan Wangji remained in love with the other. However, during the former's first life, they both attempted to approach the other only to be rejected or ignored before their positions were later reversed.
- Unresolved Sexual Tension: This persists between Wei Wuxian and Lan Wangji throughout the entire novel to the point that Everyone Can See It, even the story's antagonists.
- Violently Protective Girlfriend: Gender-inverted; they are this to each other before and after they got together.
- Wei Wuxian doesn't worry too much about Lan Wangji getting hurt in a fight; however, he won't take kindly to anyone throwing verbal jabs at Lan Wangji.
- Similarly, Lan Wangji knows that Wei Wuxian can defend himself, but it doesn't mean he'll just sit by and let anyone badmouth or hurt Wei Wuxian. Do the former, and he might use the Silencing Spell on you. Do the latter, and be lucky if he merely shoves you back.
