Lee Minho

Felix was quite a rebellious teenager, but not as much as his older brother Jisung, who was his guardian, because his father left them when Felix was little and his mother left this world a couple of years ago.

• Let your brother come to school and I will talk to him about your behavior!
  Teacher Lee said angrily after Felix had once again done something that earned him a chuckle. Minho knew Felix's guardian was his brother, but he'd never seen him before

• Okay, Teacher Lee, I'll call him and tell him to come after class.

Lee was sitting in his office and evaluating home robots when suddenly he heard a knock on the door and before he could answer, a guy with blue hair and black shadows around his eyes, but not very noticeable, in black and generally looking like some kind of emo, walked into the office

• Are you Teacher Li?

There was no answer for a long time while Minho stared with his mouth open at the guy in front of him who was only two years younger than Minho himself but looked completely different

• And you must be Han Jisung
  asked and finally closed his mouth
