Before seeing Yuki(I'm sure she's in past chapters but I forgot about her lol) I thought there was more to what Fuuko wants between Nanase and Yuni, and it's not just NTR. Like, she wants to fully break these girls because she loves the thrill of it all. But adding another girl to the mix might not be so bad because Fuuko really is manipulative, horny and evil. So, I want a twist happening since it's kinda bland for me if this manga ends in dull. I want fireworks.

Thanks for replying! But I'm afraid that's not the oneshot I was looking for. The mc was tomboyish and she met the other girl character in an empty classroom I think, and she definitely has a lot of brothers. Both oneshots are similar, so I'm sorry if I gave confusion ;_;

Maybe this one

This is the one! Thank you so much ^^

Romantic.

Hi! I'm hoping to find a manga here. I don't remember much but it's a oneshot about a girl who got a girlfriend and she has many brothers who teased her for it. That's all I could remember TT

Might be I'll Send Her Home on the Last Train, which is personally one of my favorite oneshots.
