I absolutely loved this. Ending is rushed but the decent enough. I do wonder what happened to Mochida. She's heartbroken but I think it's mostly for herself? She clearly didn't know Math Teacher well enough to be really in love with him. Hope she and Haruki realizes what it means to truly love someone. I don't think Haruki will tread down the same path. Unlike Yoru, Aya made it clear she did not reciprocate and did not give her any hope or string her along like Yoru did with Sei by sleeping with her... Also unlike Sei, Haruki has someone to confide in with her heartbreak.
Sometimes a shoulder to lean on can really help heal. I mean, just look at Sei. She repressed everything for so long but after opening up (albeit in a non-conventional way since you don't typically call your rebound your ex's name while you sex it up and they don't normally let you) she was able to find someone who loved her, flaws and all.
I love that our mains have become more confident. Sei is more comfortable in her skin because she knows what true acceptance is now. She also knows what devotion is thanks to Aya. And as for Aya, she's no longer afraid to speak out her mind and go after what she wants. It started from want but now it's clear that their relationship is stemming from need... Can't wait to read the epilogue.
Hopefully Yen Press will pick this up for English translation. They seem to be fine dealing with not so fluffy Yuri stories since they licensed Happy Sugar Life and Murcielago. Or maybe Seven Seas since they seem to like picking things up that are finished... I really want this in my collection.
