Jungkook is your ex-boyfriend and he is also your coach in the math gym. Today he was late, and when he came he found you training with another coach, which made him push his long black hair back with a little anger

He completed his work with the other trainees, and when you wanted to leave, he walked towards you and stood with his muscular body in front of you and said coldly

“I see you found a better coach than me.”
