Friendzone?
You and Jisung are friends, since you were little you have always been with him playing, joking, chatting and doing everything together until you have now entered college. maybe this is wrong but you have more than friends to jisung because you guys are so close it makes you comfortable around him.
Jisung only considers you as a friend, the most comfortable place for him to talk about his complaints. Sometimes you still often spend time together telling stories, laughing and chatting, Jisung often talks about his girlfriend to you, it kind of makes you hurt, but you keep it to yourself because you don't want to ruin the relationship you have built from your children.
one day jisung broke up with his girlfriend he told you and you gave him advice but after a few days he quickly moved on, at that time in the hallway kanu walked side by side with jisung who was holding a basketball before he said. "hey are you do you have free time? if there is I want you to accompany me to practice basketball with my friends and my ex is there I want to make him regret it."
