Honestly this manga pisses me off. Ajisai is such a darling while Mai is just overall a shitty person, constantly pressuring and taking advantage of Renako. While Renako is definitely horny for Mai (but she's horny for pretty much every girl), what she feels for Ajisai totally seems to be romantic love, with just some idealization, which is expected for someone their age, especially since Renako has always been a loner. Ajisai's arc is about Renako coming to terms with her being an actual flawed human being (even if those flaws are very very minor) and not an unreachable angel, and that she herself can learn to accept her own flaws. And Mai's arc is trying to brainwash Renako into believing she's willingly taking part in this relation and not just being sexually abused, while Mai doesn't give a shit about her personal space and doesn't know what "no" means. And we all know Mai's gonna get Renako in the end anyway, probably after minimal reflection and no repercussion for her actions.
