I didn't like the long pauses/silence. It felt like they were only trying to hit the 23-24 minute mark and every episode was filled with at least about 5 minutes of pure silence, awkwardness and stuttering.
Lots... and I mean LOTS of misunderstandings and being interrupted while trying to say something (Personally I don't mind that, I know some people don't like it so I wrote it just in case).
The acting (especially Yutaka's actor) was sometimes over the top and very awkward/overly expressive. It's not that bad, annoying sometimes though.
The weird thing was that it seemed like they weren't even dating? I watched the spin-off too and they even at one point suggested they weren't dating, I think.
That being said, I really enjoyed the story and the cute moments between the couple, it was enjoyable.
It's not the best BL but it's one of the better ones.
The silence and awkwardness sometimes annoyed me but if you don't mind that, go ahead and watch it. It's not life changing but it's not bad.
And wow... everyone in the reviews gave 8-10 stars and said really good things about it, I feel really harsh... but everyone's opinion is different, take mine with a grain of salt.
