I feel like an oddball... This is probably my least favourite of Yamamori's mangas so far, the female MC is boring and the male MC is an annoying harasser. It just feels like Yamamori wanted to do a BL series but pulled out at the last moment giving Yoi a skirt.
Last chapter is on the scanlator's page official site, it was uploaded recently. However it seems they aren't interested in uploading any more chapters of their series to Mangadex.
Well. This was so awful it makes 50 Shades feel like a Pulitzer winner. The kind of trash I thought shojo magazines didn't even care about publishing anymore.
The original novel is from the Tsubasa Bunko imprint, so it's aimed at children. That's why the protagonists are high schoolers instead of adults.
The manga is more like an alternate universe more than a direct adaptation.
