@zombieadd Older twin Himari is in a relationship with the guy for two months. She's responsible unlike her younger sister Yuzuki so the self insert didn't get laid yet. Fast forward Valentines day, "Himari" gave choco to her boyfriend. Guy asked her "what about your club activities?", she responded that it's fine and he should spend time with her at her house since her parents and "little sister" are out. Next day, the actual Himari gave late choco to her boyfriend. Cue in guy getting confused since he just did the nasty with "Himari" just yesterday. Little sister Yuzuki: Spoiled unlike her big sister. Has an inferiority complex towards her, though she's secretly proud that her breasts are a bit bigger than her big sister. Since big sister is interested in self insert, she ended up interested in him as well.

I think I'll need the TL to understand this one cuz I'm confused between the two girls (are they twins?).
