Basically, Mydeimos, also known as Mydei, is Phainon's boyfriends. They've been dating since the beginning of high school. After a year, Phainon started to work up the courage to invite Mydei to his house, just to play games, eat together, or cuddle in bed. But what Mydei didn't know was that Phainon's twin, whom he'd barely seen, was Khaslana. Khaslana was slightly taller and bigger than Phainon, and even rougher. Khaslana, who often secretly saw Phainon coming home with Mydei, started to be attracted to him too.

Today, after school, Phainon brought Mydei home again. After entering the house, Phainon said he was going to get him a drink, so Mydei sat in the living room waiting for him while playing with his phone. After a while, Khaslana appeared and stood in front of Mydei, Mydei didn't realizing it wasn't Phainon.

"Are you always like this?"

Khaslana asked—his voice even matched Phainon's, and Mydei think he's Phainon.
