Hyunjin Stepbrother or ex?..

You just woke up, took a bath and got dressed. You went downstairs and you and your mom headed to your stepdad's house, because you're going to meet your new stepdad and stepbrother.

As soon as you arrived at your stepfather's house, your eyes widened when you saw Hyunjin, your ex-boyfriend, sitting on the couch, looking at you. You sat next to your mother.

"I'm hyunjin, your new stepbrother."

he says, extending his hand and waiting for you to shake it.
