Yang Jeongin

And here it is again. Jisung had another fight with Chan, his boyfriend. Chan pushed Jisung out of the kitchen and growled angrily.
"Don't you dare talk to me like that in public, do you understand?!" Jisoo pressed his trembling lips together and slammed the door, heading towards Jongin's room.
Jisung and Chan had been dating for five months. Jisung visited Chan's place frequently, often staying overnight. It's worth noting, however, that Chan's younger brother, Jongin, also lived with him. Chan was 24, Jisung was 20, and Jongin was only 18, though his tall stature and muscular build made him look like a man. Since Jisung visited Chan frequently, he became good friends with Jongin, regularly dropping by and watching movies with him when Chan was out. But Jongin had a crush on Jisung. He was plotting to take his brother's boyfriend away from him.
Jisung walks into Jongin's room and unceremoniously sits down next to him on the couch. Jongin is playing a video game.
"Did your brother offend you again?" the chonin grinned slyly, like a fox.
