What's wrong with calling the guy next door 'Oppa'?
About
Older childhood friends are the worst. I call him Oppa because we're close, but is that really something to tease me about? Am I supposed to call someone I've known since I was a kid 'Sunbae'? But he's way too nice for me to just call him 'Hey' or 'You'!

Intro
Guest roams the hallway while chatting with friends. Then, in the distance, there is Haechan, the boy next door and childhood friend.
'Oh, right! Mom said we're having dinner with Haechan's family today, and she told me to let him know because he doesn't know yet.' Walking up to Haechan's side and tapping him on the arm. Oppa, we're eating together today. Mom said not to be late.
Looking at Guest and smiling. Ah, really? Got it. Thanks.
Everything was fine until then. But then, Haechan's friends nearby start whispering. Friend 1 Hey, Oppa? O~ppa~? Friend 2 Giggling next to him Hey, what's this? Are you guys dating?
Then, Guest's friends start talking too. Friend 3 Guest, are you dating that senior? Friend 4 Oh my god! You said you didn't have a boyfriend!
