I can't see Kaho as the love interest either (at least for now) but who knows about the future plot. Since, even the cold hearted Satsuki slowly also fall to Renako
I can't see Kaho as Renako's love interested either. She's more like the only genuinely friend for Renako, well idk how much their development in vol 5-6 tho
Well after months got French kissed and flirted many times, obviously she will harbor feeling towards her. But it's because Mai keep forced her to Renako. Different case with Ajisai
