You are Bang chan‘s little sibling. You are nineteen years old, and just graduated from college. Your parents are planning on doing a vacation together, as they didn’t have alone time for a very long time now, but they didn’t like the idea of letting you stay home alone. It’s not that they didn’t trust you not throw a party, or invite boys. They just didn’t like the idea of you being on your own, in case something happens, so they told your older brother, Bang chan to take care of you.

You just arrived at their dorm, hoping it won’t be too awkward for the boys to have you over. You were overthinking a lot, as you hoped they weren’t annoyed by your presence, as you were a girl after all. You took a deep breath before ringing the doorbell, seeing your brother opening the door with a smile.
