First I'd like to note that the subs were out of sync 95% of the time (different sources so too much time needed to resync) and the other 5% I didn't look at them lol. so some details might be slightly mixed in my head.

It was an alright drama, been about 2 months since I've watched a proper J-Drama but from memory, this plot is pretty average. You could say it flows similarly to 29th Christmas with the kind of plot developments, but no where NEAR as annoying and melodrama filled. Nothing that good stands out with the story, because it's so average, but the bad pacing does stand out.
I really disliked the fact that Chigusa and Taketo (along with the secondary couple too) kept on having trust issues and breaking up then getting back together basically every episode until the very end. I'm surprised though how they managed to not make it overly dramatic with this kind of story lmao.
Acting and all that was good, Yoshino's (Chigusa) acting felt well above par while everyone else had the standard Japanese drama acting. Masaharu's (Taketo) acting bothered me mainly because he seemed to slur words together like every other sentence, same with his dad but I'm just gonna write this off as being an element of the Kyushu dialect (which I've never heard prior)
Etcetera etcetera standard production quality of 90s J-Drama, good music, etcetera etcetera.
Overall it was alright, good time killer if anything, but nothing unique like Koukou Kyoshi. Could have easily been 8 episodes
