This is my second reread, however, I still cannot quite understand what Mei meant when she said “I’ll be gentle. It’s your first time, right…?”. Obviously I understand the implication but what confuses me is the way she says it; Could this be some sort of hint that Amemiya had already taken her first time, so by falling back unto what she knows in this case all the things that had been done to her, she does the exact same to Yuzu in effort to be accepted and needed by her? Mei does say “I want you to need me. Could you do that?” And then she goes on to say “You’ll accept me, right?” And then obviously that is when she says she’ll be gentle as it is Yuzu’s first time. This may all just be me overthinking it but I would gladly appreciate someone else providing their input on the matter
