[Two Male Leads + Pure Romance + Both Have No Past Relationships + Intense Romantic Push and Pull]
[Funny, scheming, possessive, green-tea top x Pure-hearted, gentle, introverted, top-student bottom]
Si Xu had been single his whole life and was the kind of exemplary student everyone else's parents wished they had. The idea of "dating" had always seemed far removed from him.
But the more you lack something, the more you want it. During a college mental health class, the prompt was, "What did it feel like to fall for someone for the first time?" His classmates' answers only strengthened Si Xu's resolve to start dating.
Xia Xun, Si Xu's childhood friend and only close companion, was more than happy to take the lead on this, especially since he was already looking forward to it. He was doing it for his buddy, or so it seemed. In truth, he was doing it for himself.
Xia Xun: Xiao Si, I've got a great way to help you!
Si Xu: What way?
Xia Xun: Pretend to date me.
Si Xu: Huh? That doesn't sound right. We're good friends!
Xia Xun: That's exactly why we should help each other out.
Xia Xun: I don't want to make things hard for you. It's all my fault for being a guy, and for getting bad grades! (Overcome with grief)
Si Xu: ...Fine, let's date! But let's agree to break up if either of us meets someone we actually like!
Xia Xun: No problem! (Not even pretending anymore)
Xia Xun, to himself: How could I ever break up with him? I've waited so long for this chance. Now that I've got you, you aren't getting away, Xiao Si Xu.
P.S. All characters are adults. There are angst-filled moments and a side couple. The characters aren't perfect, so don't bring your real-world values into the story.
