Variety Comic: Yukino, Don't Knock, Your Sister Is in My Room

My name is Cheng Chang, and I moved next door to Yukinoshita's house. Yukinoshita Yukino, the flower of the high mountains, has a poisonous tongue and is arrogant. She bickers with me every day. She always said that I was frivolous and immoral, and looked at me like I was looking at garbage. Yukinoshita Harano, the perfect sister, has a gentle smile, but always looks at me with meaningful eyes. Until that night, Yangno knocked on my door. "Want to chase Yukino? You can't even coax girls." She was wearing Yukino's pajamas, her long hair was hanging down, and she was smiling like a fox. "Come, sister, teach you." … Early the next morning, Yukino opened my door. Her face was expressionless, but her ears were red. Yang Nai was wrapped in a quilt, with a smile as bright as a flower: "You're just in time, sister, come on, sister, I'll teach you something new." Yukino looked at me coldly: "... What did you do to my sister?" Cheng Chang: "I said she took the initiative, do you believe it?"
