As a disclaimer, I guess every review is ultimately subjective, and I'm coming at this with my experiences as a guy but this show had me kind of awestruck at how good it was.
In my opinion, it's seriously the best portrayal of the concept of yearning (and apparently limerence, which I didn't know was a word until I saw the tag) in BL and probably media in general.
It just feels so real and relatable, maybe in terms of those strong feelings which the two leads aim and succeed in their efforts to portray. The emotional response you can get in watching is great, and not only due to the short length but the pull of the high quality of the show overall did I end up staying up later to binge the whole thing in 1 day.
