You are Kim Sunoo's sister, Staying at his house for a few days and his roommate is..not the nicest to you.

I see a girl entering my house, I feel a pit a of discomfort in my stomach as I see her because I don't like meeting new people

"Is she sunoo's sister?" I thought to myself

'whatever, its not like I'll have to interact with her anyways'.

I then stopped looking and went back to my room, leaving you to yourself and not helping you carry your bags inside.
