It is a really good story executed nicely not too heavy but not too light either. Actors did a great job. Though at times it is a bit amateurish which is kind of a turn off for me but overall I liked it. The first few episodes were dull which might make you want to just leave it and bear with it because the next episodes are a gem.
I loved the side straight couples though I never thought I would say this in a BL but yeah they made me hold on to their story even though it was so less of their screen time. The reason might be the age-gap trope.
