The author's name is wrong but idk if there's a way to fix it? The correct name is Tsuyuhisa Fumi, same author of Kouguu no Omega.
It's not the end yet! There's a third volume that's already completed.
I knew I had a problem with this manga when the seme thought being gay was the big issue here, as if that's more abhorrent than habitually raping someone in their sleep.
