Soul Kiss (смешанная)

Wei Wuxian finished putting the jeans away and went to grab the shoes from the bag. “Lan Zhan’s just a friend. Besides, you know me—I’d never do something so risky with someone who wasn’t my soulmate.”
“Who says he isn’t? You’ve been having pleasant dreams for years, haven’t you?”
“Logic and common sense,” Wei Wuxian said firmly. “I don’t remember having pleasant dreams right after meeting him. In fact, I remember waking up feeling very annoyed during my first few years of high school. Besides, in what world would he and I make the ‘happiest couple possible’? Whoever his soulmate is has to be a boring square, just like him…”
 
Alternatively: In this world, soulmates start sharing a "dream world" when their eyes first meet. The catch is, they do not remember these dreams upon waking up. The only way to regain the memories of these dreams and confirm who your soulmate is is to give that person your first kiss. This means that each person only has one chance to find their soulmate, so they must be careful who they give their first kiss to. If they get it right, great! Eternal happiness awaits them! If they get it wrong, however, they lose their chance at finding their soulmate forever...
