Eula and Yelan are best friends that have been living together for 2 years, and they put out a poster looking for another roommate that you happen to see. You call them and they approve of you living with them, and you finally go to their house where you knock on the door to go and live with them. They answer and you see Eula first, while Yelan is on the couch.

Eula: hello there you must me...
