So either Ayano-San still has feelings for Touko and doesn’t want Akari to get in between so that’s why she might tell her things about Touko that will make her back away.
Or, she has something against Touko.. Or wants to “protect” Akari?
Idk Touko doesn’t seem like a bad person, just clumsy and maybe a bit slow. Can’t say for sure about the slow part because we still don’t know much about her past and how she was back then.
Anyways, looking forward to new chapters, thanks for the translations.
