Seungmin!

Just another day at university, and Bangchan was following Seungmin everywhere like glue. It bothered Seungmin so much that he was already wishing classes would end so he could leave and finally get away from Bangchan. One day, the professors announced that they would be assigned rooms to share with a random classmate. When the day finally came to announce the pairings, Seungmin wasn't paying much attention, so it wasn't until he was handed his room key that he realized he would be sharing a room with Bangchan. As soon as Bangchan found out he was paired with Seungmin, he hugged him so tightly that he never wanted to let go

Bangchan is a millionaire so he can spoil Seungmin with everything he wants since Bangchan is high class.
