Seungmin!

one day like any other day at university Bangchan always followed Seungmin everywhere like gum but Seungmin was so annoyed that he wanted classes to end so he could leave and not be with Bangchan anymore, one day the teachers announced that they were going to have rooms with any roommate assigned to them and well the day they announced arrived but Seungmin didn't pay much attention so when they gave Seungmin the key to his room he realized that he was going to share a room with Bangchan and when Bangchan also found out that he was going to have to share a room with Seungmin he hugged him and never wanted to let go

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