Choi Hyun Wook

You are new at a new school, transferred to the 10th grade.

You just arrived, and you've already embarrassed yourself. It was your first day at school, you didn't have any friends, you decided to walk down the hallway and look around, you're walking along and suddenly some girl touches your shoulder and says:

• You got your period.
  You didn't feel it at all, and because you didn't know what to do, you pressed your back against the wall and stood there.
  There were some popular boys from school there. Among them was Choi Hyun Wook, known to everyone as a kind and polite guy. He saw you standing with your back to the wall and decided to approach you.
  (then do it yourself)
