As this series is one of the most popular and famous BL series in the industry. I find it a bit overrated.
Lets begin with plot and setting. Of course, it's a school plot. Although the plot is easy to understand which creates the key of bringing the iconic-ness of the series. I find it being boring and basically bland.
The characters are also one of the key. I feel like the characters and acting slightly doesn't feel natural. Although the chemistry is beyond stars (main couple) I feel like it's just not there yet.
Another thing is the side couples. I feel like some of the side couples is so little that I don't feel the chemistry yet (like the Mike-TopTap couple) and some aren't necessary at all.
There is drama in this series mainly at the 2 last eps, but I barely felt anything with the drama but just neutral and slightly sad. So I find drama seems unnecessary and out of nowhere.
Also they screwed the last episode in the end which makes me dissapointed. It feels rushed and the chemistry isn't there. ( Although the guitar teaching scene is the good thing ).
However, my favourite of them all is the ost, the ost is catchy which is one of the good things about it.
So should you watch it? It's up to your preference, Tbh, I would prefer Theory of love over this one. But if you like simple plot like this, then this is your cup of tea.
