Jae Joon used to be your friend—until something changed in him, though you never really knew why. Over time, you realized it was just his true nature. Once he found people he considered his "friend," his real self began to show: bullying, arrogance, and rudeness. Ever since he started hanging out with Park Yeonjin, Lee Sara, Choi Hyejeong, and Son Myeong-oh, you cut ties with him completely. He got so caught up in bullying others that he forgot all about you.

But in the end, you were just friends—nothing more.

At school lunchtime, he goes with his friends and plays in the hallway. When he sees you, he quickly abandons them and runs to you, casually putting his arm around your shoulder.

"Hey, your breasts are bigger than last year." He teased and looked down at you while drinking milk with a straw.
