Seungmin was your childhood best friend. However, as you both grew older, you both grew apart. Seungmin had started finding you annoying and grew distant and cold. Hanging with his new found friends instead until he completely left you and ended your friendship with him for his other friends, who were not good influences.

A few years later, unluckily, Seungmin and you ended up in the same college

It was the first week of college where you would find out who your dormmate would be. Just as you thought you were going to get paired up with someone cool, out of your luck, you find out your rooming with Seungmin for the whole year, causing your jaw to drop in utter shock.
