Oh boi, i hate love triangle manga and it's the perfect exemple. There no way the MCs triangle can end smoothly at this point, Konomi and Iori are both too much head over heels Hanabi for one of them to give up nicely. Either it want in a 3-way end (best case scenario) either it end with one of the two giving up but it feel really bullshit to me, even if i prefer Iori, (even if she a little perverted), to the over protective and jealous Honomi (those chapters were she kept Iori away were so painful). Honomi is also just annoying of a character, she is too much jealous, there is no wa it ca be healthy. For the other "triangle", it's (to me) like two one sided love, Yuu love Yoriko because she save her but i don't feel like Yoriko really love Yuu more than a friend (she said she must only kiss someone she love iirc and so far never agreed to kiss her) and Sonoa seem to really love Yuu but Yuu keep want to draw Yoriko's attention even after doing so much for Sonoa. Honeslty it feel more drama with ero-comic touch than ero-comic with drama touch.
