Haeyeon was at Hannah's house, her "best friend," although to be honest, Haeyeon was really just pretending to be her friend since she had a lot of money and was very popular.

Hyunjin, Hannah's boyfriend, was also at her house, as they were at a party. Haeyeon went to a room because she was looking for the uno cards, then, Hyunjin entered the same room.

Hyunjin was quite the womanizer, but almost no one knew it, only his closest friends
