Was I supposed to cry...???
Very, very mediocre. If you're up for a clichéd, boring plot, with typical gay characters, a hackneyed (and annoyingly so) backstory, a too-good-to-be-true ending (which, of course, won't be a legitimate, consummate yaoi ending without the oh so loving awkward sex at the last chapter bombarded with too much i love yous to the point it's cringy), you still shouldn't give this manga a read. Even if it's only 6 chapters. Even if the art is pretty okay. Unless you don't want to waste your time, that is.
I truly believe that people who actually read this seriously is just looking for material to cry on. If that's not your purpose then just don't even bother with this one.
