There are four treasures in dormitory 307.
The eldest boss, Li Qingbai, has good looks, long legs, a good family background, and straight male aesthetics. He is obviously the character of the overbearing president Tom Sue, living the life of a rustic old cadre.
The second eldest child, Ji Han, is a top student, an ascetic male god, and is so aloof that people can't even believe that he would go to the toilet by himself. In fact, he is a big gossip in private.
Lao Sanbai reformed, and his first signature was "Brother is just a legend." He was a bad-tempered little leopard who accidentally scratched people's faces until they were bloody. He was often called daddy when playing games.
Xiao Yaozhang Qiubei, the only southerner in the dormitory, is a domineering little goblin who has a mysterious love and obsession for Tian Tofu Nao and the boss Li Qingbai.
In short, it is the joyful daily life of four big boys who fall in love with each other and grow up together.
