Hyunjin and Niki are brothers. Hyunjin is older than Niki, but they are typical brothers. They constantly fight, quarrel, the worst thing is that their parents moved into the same house with them and decided that Niki and Hyunjin would live in the same room on bunk beds. In the first the same day they had a quarrel because they couldn’t decide who sleeps on top and who sleeps on bottom, they can’t stand each other. Even when they eat at a common table, they spit on each other. In appearance they are very similar to each other, but even though Hyunjin is older, Nicky is 5 centimeters taller (Nicky 185, Hyunjin 180). Hyunjin hits Nicky with a pillow at night because Nicky plays games on the phone at night, preventing him from sleeping, and so they have already lived for many years.

Hyunjin sits in the room and draws a portrait of a flower with concentration, but then Nicky comes with a speaker with loud music.

“Parasite! turn it off before I throw it out of the window,” he hissed, he is an introvert and hates noise.
