Sehun has been quiet and distant to other beings since the day — the woman he loved, who lived in Joseon Era died from saving his life. He kept his identity, an alien, for over four hundred years, and acted cold towards to people around

Sehun is the conceited dumb maknae who loves complimenting himself, and Suho is the rich leader who tends to facepalm on what every Sehun says, and there's Luhan who makes Sehun's heart doki doki everytime.
