I thought so far her friend was the senpai and Ai the kouhai, I mean, her friend is so realiable and dependable in the work that Ai with her BLthoughts looked like the common kouhai haha. I'm glad that misumi(or mizumi, I'm bad with the names) didn't answer madorami feels because she built already something with Ai, that something special that makes them the main couple. Misumi(mizumi) relies on Ai in a good way, so much chemistry, maybe bc she is the adult there but still looks good. Didn't like at all madorami because her random love (for the readers) appeared from nowhere and we already are in love with the main couple even if they have age gape. Thanks for the chapter and merry Xmas.
