My English is not good enough for that last chapter, I missed too much to make sense of it. Does anyone know where I can find the raws so I can puzzle it together? Or give me a short summary, that would be amazing:)
Honestly I didn't fully get it either as a native English speaker, what with the twins and weird vocabulary that even I had to look up, I tend to kind of speed read through every relationship that isn't the two mc.
Anyway, the summary I got was that, after Watanabe found at Ririka (the gyaru) liked her, she avoids her at school all day. Then one of the twins pulls Watanbe aside to chat with her. While they're talking, the other twin comes along and says she couldn't have tea time with her onee-sama at the green house, because her onee-sama invited another upper class man along, and the twin felt that she wasn't cool enough to hang out with them. Her twin convinces her to go back, and also they said they loved eachother, honestly I don't really understand it either. Anyway, the twin that wanted to chat with Watanabe basically said that the drama between Watanabe and Ririka won't be fixed by Watanabe ignoring Ririka. So Watanabe goes back and convices herself that she should only look at gay girls, not be a gay girl. Then Ririka confronts her and says she'll convince Watanabe that she loves her.
