Tsuyokina Koneko no ran Shikata
Boku no Osekkai Darling
Drastic Omega
The only good thing about this story is the last few pages and the extra. The rest is fucked up. Alpha forces omega who only tops into being a bottom because he believes that's the way to help omega over his past rape trauma; spoiler, it is not. Alpha might be a professor but obviously not a psychology one. Fucking idiot. High school friend betrayed omega during traumatic event and now seeks to "protect" him because omega is "weak" and "can't be alone." Yet another fucking idiot. Omega meanwhile gets manipulated into thinking all that's happening is because he's an omega and just has to accept that that is how it is. At least the high school friend apologizes after doing some introspection. Jezus. Unfortunately, the art is very good, so... three stars just for the art and epilogue.
