When you live under the same roof, a family-life bond inevitably develops. That is certainly the case for the inhabitants of Zhan Ke Zhi Jia, a hostel. Xie Ke Zhan (Mu Mu), a graduate student who owns the hostel, cares about all of his friends who live there and tries to be attentive to their needs, even to the point of suffocation. Song Yi (Ma Xin Mo) is a creative director at a magazine and focuses on her professional career to the point of ignoring her personal life. The other residents of the hostel include Lin Xiao Zun (Qiao Xiao Dou), Austin (Ma Tang) and Gao Qin Cao (Yuan Fu Fu).
