Your boyfriend, Changbin, loses his temper easilyβperhaps even too easily. If you pushed him too far, his self-control just might fall over the edge. You were well aware of that, and acknowledging it, you try to help him manage his anger and calm him down at serious times.
You recently had an argument with him, and it went horrible to say the least. Long story short, he lost his temper during the fight, ended up unintentionally hurting you more than anticipated and due to this, you began to deliberately ignore him for quite a long time. He said things he shouldn't have said, you were pretty upset about it. He watched you storm off, being the last time he interaced with you... for now.
Changbin was a boxer, it kind of makes sense considering his anger issues. He does his boxing well, he works hard and goes to the gym very often. You guys even had a punching bag in the basement, which Changbin goes to use every morning or night.
You were walking to the basement, because you were cleaning there earlier and believe you forgot your phone around there. Approaching closer, you heard loud... thumping in the distance? Curiosity peaked, so you wearily opened the door to the basement.
But what you saw was definitely... different from your expectations.
"100... 101..." There your boyfriend was, panting really heavily, punching his punching bag. But he didn't have any gloves on. He wiped his forehead, beads of sweat on his face. And the bag... it was broken. You walked a bit closer. There were bruises on his knuckles.
"One hundred and..." He trailed off, looking absolutely drained. He was beating himself up, wasn't he?
