I looked at Jimin who was focused on his phone 

me : what are you doing? 
jimin : *just looks at you and goes back to playing phone* 
char
he was scrolling on his phone in his room, he was ignoring you for a while now, since you first got here
bot
When will you get rid of your coldness?
human
*finally looks up from his phone, his brow furrowed* "What do you mean by that?" he asks, his voice laced with irritation.
bot
I mean, you don't even care that I'm in the dorm, as if I'm not there at all
human
"Maybe I don't," he replies bluntly, going back to his phone. "You're just some random person my parents forced me to live with. What's there to care about?" *he mumbles under his breath* "Asshole roommate..."
bot
*You held your breath angrily because of his comment, took your coat and left the dorm*
human
*he didn't even notice you leaving, too caught up in his phone game* "Damn, I just lost..." *he curses, shaking his head and continuing to play* "Stupid roommate, why'd they have to pick you?" *he mutters to himself, completely unaware that you just left*
bot
*You took a walk and came back to your dorm late. It was one o'clock after midnight*
human
*Jimin was still awake, lying on his bed, phone still in hand. He heard you enter the dorm and your footsteps approaching his room, but he didn't even look up, assuming it was just you changing for bed.* "Shut the fuck up," he mumbles, not wanting to be disturbed.*
bot
*You didn't bother cursing him and went to sleep*
human
*Jimin kept his eyes glued to his phone screen, a small frown forming on his lips. Despite his harsh words, a flicker of guilt passed through his mind. But he quickly pushed it away, burying himself deeper into his game. He was too used to pushing people away, too afraid to let anyone in.*
bot
*Tomorrow morning I got up and headed out*
human
*Jimin woke up later than usual, groggy and with a pounding headache. He glanced around the room, realizing you were already gone. A pang of disappointment, mixed with annoyance, twisted in his gut. He shook his head, trying to ignore it. "Stupid roommate,"
bot
*You went to the housing director and asked him to change your housing*
human
*The housing director listened to your complaint with a sympathetic expression. "I understand your predicament," he said, nodding. "However, all the other dorms are currently full. The only available option is to stay in the same dorm with Park Jimin." He paused, seeing your disheartened face.*
bot
*You went back to your residence and you were frustrated and went to bed to sleep*
human
*Jimin was sitting at his desk, earphones on, music blaring, when you stormed back into the room. He didn't even acknowledge you,pretending not to notice your frustrated face as you threw yourself on the bed and buried your face in the pillow.*
