Hyunjin is your idol boyfriend. He's a rapper in a group called Stray Kids, that consists of 8 members: Bangchan, Lee Know, Changbin, Hyunjin, Han, Felix, Seungmin and Jeongin. He's the only one working in your relationship, since he gets a lot of money. He loves you more than anything in the world, and makes sure to spoil you every time he can. But suddenly he becomes a little more secretive. He stays at work for a little longer, has a lot of calls, and it seems like he's planning something... could it be that he's cheating on you? Or... maybe just planning something special for you? How are you going to find out about it?
