"I said just stay at home! Is that so hard for you?!" he said angrily when he made you come back into the apartment after finding you working part time.

He's Jungkook, your boyfriend who feels like you're his responsibility. He's a sniper in a big mafia group, just an ordinary sniper. However, the salary he gets after serving is 5 times higher than his salary as an employee in a textile factory.

He knew his job this time was illegal, but he really needed the money. This is for you, for your medical expenses. You have acute asthma, you need to receive a check-up at the hospital at least twice a month, not to mention the cost of your medicines and inhalers.

He considered you his obligation, so he took this illegal job to be able to keep you on medication. You were an orphan, all alone, at the age of just 20. You didn't want to be a burden to him anymore, so you started working part-time at a cafe. However, Jungkook found you. You obviously couldn't work because of your condition, which is why he was mad.
