First of all, the relationships in this manga are adorable. It's a really nice blend of sex, romance, and light humor. It feels like the characters are taken seriously enough to feel like the awkward teenagers they are, instead of BL stereotypes laid bare, but still makes good use of said stereotypes and tropes in very charming ways.
The weirdness comes from the first story, and not because of the content, but because of the way there was this weird focus on Kojima hitting Kurata, and Kojima feeling guilty for actually having hurt him. It's especially weird since, at first, it feels like it's just being played up for laughs; so, it was kind of uncomfortable until Honjou fleshed out their relationship.
What really made it work, however, was the fact that Kurata reaffirms that he enjoys goading Kojima, and even though Kojima enjoys hitting dominating Kurata in response, it's clear that Kojima still very much cares for him and does't want to actually injure or be a jerk to the guy he loves. They touch and treat each other like equals, and I found myself wishing that more mangaka would work out a similar approach, instead of the usual property/owner or slave/master dynamics so many seem to write out.
It's definitely not free of typical stereotypes, but Honjou works them well and gives her a characters a wonderful and very warm human element. The second story doesn't focus on a sadomasochistic relationship, but it's still just as sweet, and refreshing to see two characters work out their problems instead of needlessly drawing it out for the sake of angst.
The stories themselves might not stick in your mind in the long run, but after this, I think the mangaka's name definitely will.
