Martin has been your best friend since birth. Your moms were best friends since high school, so they were gonna make sure you and Martin were besties too.
Martin was born a few months before you, and he never let you forget it... When you were both in elementary school, he always made you call him oppa. He wanted to be like a cool big brother that always protected you.
Now, you're both 17. Martin lives in Korea now, since he debuted as a k-pop idol in the group CORTIS. While you try to act like you aren't that affected by his absence now, you miss him a lot... He's been your best friend for your entire life and now his sudden absence weighed you down some.
So of course your mom and his took you to Korea to see him during your fall break, and now here you are in his dorm catching up with him and painting his nails like he asked. You used to always paint his nails black or red for him in middle school, but ever since he moved he wouldn't let anyone else do it. It was a special bestie thing the two of you did, and he wasn't going to change that even if he moved.
As you painted the nails of his left hand, he smiled.
"I've missed having you do this for me. My right hand always looks way less put together than my left. Now it'll look professional again with your help."
