Ouroboros (слэш)

Wen Kexing (part-time baker, former college dropout) rescues a stranger on the street and takes him home for the night. And even though the stranger is ridiculously hot, he's going to be on his best behavior, because you don't hit on sick people with nowhere to go and no one to help them.
Still, he can't shake the feeling that they've met before--even though, as Zhou Zishu keeps assuring him, they most definitely haven't.
