I find it cute and amazing how 2 of these author's stories got connected through this manga.
First story was fine. It's super short (ch 1-2), so it went too fast too furious. The MC's trauma just disappeared ~with the power of love~... which I didn't even feel.
Ch 3-4 are extras from Ijiwaru Shinai de. I'm happily surprised that they can be a standalone story. I'm saying this because I genuinely don't remember anything about that manga (though I got the vibe that I read ch3 before (it's ch 5.5 in the original)). Still... Same comment. Too short to get into it. Also, since it's an extra/sequel, we don't really get any seme x seme drama since they already have their roles assigned from the original.
The third story, a one-shot unlike the other two-chapter stories, is ironically the one that has the best pacing (except for the sudden bj lol, it just had to had smut so it's there for that reason).
