As September comes, a new semester has begun at Shan Ming High School. The school doctor, Song Yue, has also welcomed a new roommate - canteen chef, Xu Xiaodao. Mr. Song thinks Xu is like the "Snail Girl". Ever since he starting living here, the dorm has been super clean. Not only does he clean, he also cooks all the meals and does all the laundry! This is truly suspicious! Things get even weirder when Mr. Song realizes Xu Xiaodao knows a little bit too much about him and is a little bit too clingy. Furthermore, Xu Xiaodao cares for him way too much?? Things are not as simple as they seem...Artist’s weibo: @_mudage
