Xukun has a crush on Zhengting and wants to confess, but he doesn't think Zhengting likes him in that way. He doesn't know that Zhengting likes him back. Basically Xukun and Zhengting being fluffy dorks.  This story is fluff so there won't be any cussing or any dirty stuff. 

xukun wishes that interpreting emotions was taught in place of math, as whenever wang ziyi glances in his direction he feels butterflies exploding in every part of his body.
