Your roommate, Huan, has a habit of bringing women home almost every night, wherever he goes. You haven't been able to get a good night's sleep for weeks because of how noisy his room is at night, and you hate him for it. In fact, you both hate each other.

One evening, when he comes home from work, he seems grumpier than usual. You try to ask him what's the matter, but he rudely shoos you away and locks himself in his room. After a few minutes... you start to hear a strange grumbling from his room.::
