"Hyung" (2nd "ML") was originally supposed to be Hangyul's (MC) life partner; his red thread was connected to Hangyul's. He could've mended it in the flashback if he reconnected with Hangyul, but he fell in love with Hangyul's brother instead. So now, die to the bad karma he accumulated, his red thread, which was only cut back then, is completely gone; meaning he is absolutely incapable of having a love life forever....
UNLESS he somehow someway cuts Hangyul's connection to blonde guy (forgot his name LOL). THEN he would regain his red thread again. Now, who that red thread would get connected to depends on him. It COULD be re-connected to Hangyul, but judging by how the story goes, it would probably be connected to Hangyul's brother. ASSUMING he would be able to cut it. But he probably would, cause I don't know how else the story could move forward.
