jay said on days when he couldn't work out, his chest and shoulders would feel itchy. when he lies down and sees the ceiling, it reminds him of the bench press. he would say to himself that he should have worked out today bc his muscles are shaking that he couldn't sleep.
Before Jay debuted, he really loved going to concerts a lot. While he was still a trainee, he attended BTS concerts many times, he attended BTS Wings tour with Heeseung 3x, BTS Love Yourself concert with Heeseung, Jungwon & Sunghoon, he also attended Maroom 5 & Ne-Yo concerts.
