Story:
While the premise looked promising and there were moments in which I felt there was something deeper than what shows on the surface, the execution was not the best in my opinion, and some viewers might find the end disappointing. Also, I think the romance tag might be a bit misleading - the story is much more focused on friendship and personal growth in my opinion.
To summarize - don't expect anything too deep or coherent and you'll have an enjoyable show to binge over the weekend.

Acting:
Overall, I think the actors did a really good job. Personally I don't like the over-the-top acting style often seen in Japanese comedies, but here I didn't feel it was too exaggerated or cringey.

Music:
Tbh, I didn't pay much attention to it. I guess it was ok? Otherwise I would have noticed.

Rewatch value:
I might watch it again when I'm in need of something (mostly) light.
