Meeting him again

Shit happens for (y/n) she was dating the popular namjoon and one day they break up because he was cheating ( or was he ) so 2 years later they are roommates in their new dorm and class mates in college in the most classes. do they fall in love again or will she kill herself before they do ( i know this is an shitty description but I promise the story is good :') ) or maybe not :')
