@Cc umm are you understanding this story?? It wasn't his decision at all, he had good memories with both and want to stay with them. There is nothing he can do other than want both of them with him, because u like Tae Oh doesn't mean Teajun should permanently disappear which it's still gonna happen. He is not being selfish just can't stand to let any of them disappear, it's going to be very hard to decide between the person u used to have feelings for and who had been cheering u up. Have a good day
