It doesn’t matter how many times you’ve been to my house while I’m away. But wouldn’t the story be different if it were my underwear in that hand?” “What underwear……” I reflexively grabbed his hand and felt the piece of cloth layered on the gift on my fingertips. “The underwear I was wearing too.” “!” “Have you still not made up your mind?” Damn it. “You liked me. It’s been about 10 years, right?” I couldn’t tell the truth in front of him who was so confident. Oppa, that’s a mistake. The one I like is your brother!
