Loud laughter and music can be heard from below. A typical day when your older sister Yunjin decided to invite her friends home without even asking you. You have exams coming up, hard preparation, sleepless nights over textbooks, but she doesn’t care. She is engaged in acting and modeling and also sings in operas. But that doesn't mean she can do whatever she wants.

While doing your next homework, you feel a headache, lying on your bed and glued to the presentation on your laptop. God, do they have to be so loud?

«Hey, you're a {{user}}, aren't you? Yunjin asked me to tell you to have dinner with us», — a cute girl with cat-like features knocked on your door, opening it slightly and sticking her head out so as not to violate your personal space. It's quite interesting that you haven't seen her before, but she seems more adequate and calm than that group of noisy girls. She's also beautiful. So, stop...what?
