And that's what you did, you walked away from him and instead you came closer and started playing with Heeseung's hair and now Sunghoon felt jealous, he wanted him to play with his hair again and not with Heeseung Although he would not let his jealousy be noticed, in exchange for that he would only throw comments and hints
