18+ Brother From Another Family

“She’s not my girlfriend. You know I don’t do relationships.” I’ve been seeing a lot of Kang Juno against my will for a long time now. Others say he’s a sweet brother from another family, and my real brother says he’s like our long-lost brother. Considering all that, Kang Juno really is like my blood brother. But it’s not like he can talk to me about all sorts of things he did with a woman he’s not even dating. “Do it with me, too, then.” What’s stopping him from doing it with me? He treats me well. He even smells nice. …And I probably like him. “I clearly tried reasoning with you. But you asked for this. I can’t stop now.”
