The story idea is good, but several flaws drag it down.

I get that Fumiya is trying to save his relationship with Ritsu by pretending they weren't dating... but why does he never try to start a new relationship? He keeps insisting they're just friends even when it's clear Ritsu likes him. Ritsu, on the other hand, never just guesses they were together even though it should be obvious. They live together and yet there's only one bedroom? Fumiya sleeps on the couch every day. All their clothing is in the same room, to the point that Ritsu grabs Fumiya's sweater thinking it's his own. And you expect me to believe Ritsu never got curious about that?

Their reason for breaking up is a good one if you put thought into it, but it's not executed well so it felt a little pointless. However, if the relationship was truly that strained, Fumiya wouldn't have been so unerringly in love with Ritsu anymore. Basically the two plot points don't match well for me.

Other reviews have said the chemistry is good, and yeah the two guys get along well and they didn't have a problem being in each other's space, but I'm not sure I'd say their romantic chemistry was good. Their kisses felt like a caricature of real kisses - the barest press of faces in a lip-oriented location. Their first time having sex had an awkwardly blocked hand on what I assume was meant to be Ritsu's crotch, but the lack of reaction or motion made it obviously unrealistic.

Overall, the show had some good moments and a good premise, but the execution wasn't always well done, the acting was passable, and the scenes don't entice me to want to rewatch the show.
