Honestly, I don't have much to say about this series. I knew some of the actors, so I decided to give it a chance. I will only expose my opinion, but I want to make it clear, that I really respect the personal opinion of each person, and also respect their tastes and preferences, regardless of the genre of the series, being BL or not.

This particular drama, I did not find interesting, even the issues addressed, in fact, is like any other BL series, it's more like they copied a scene from each series and made an adaptation, and see, I watched very few. The story had nothing different or innovative, and was even confusing in some moments.
Chemistry? There were indeed moments when Fighter and Tutor showed chemistry by their reactions, however, their relationship seemed to have more lust than love. I believe, that they should do more work on this storyline, and honestly, the pandemic is not an excuse for a failed storyline. The second main couple may be considered cute, but there is nothing interesting in their story.
In this Drama, there was absolutely nothing that hooked me.
As I am fair with my evaluations, from my opinion, it is worth pointing out that Zee was expressive in his character and Saint's acting, improved a little, he acted better as Tutor than as Pete, but he still has a long way to go, his acting is good, but not great, maybe because the characters he plays have some similar characteristics. The moments that he stood out for acting with a different characteristic, were in the Hot scenes and only! But for me, sex scenes are irrelevant, I consider the content more. Even if they have many hot scenes between the characters, it's not a problem, the main issue is when they emphasize too much these intimate moments between the characters, than to show how their relationship develops, for me the chemistry between FighterTutor only came down to sexual desire, and only this is not enough.
The second main couple, I can't tell, but in many moments they seem like beginners to me.
Regarding the rest of the cast, what is the need to adapt many couples? There is no point in having a great cast and good actors, if in the end, the story of none is well worked out. This storyline failed miserably!

An interesting point that I have observed following the comments, and the reviews, is that a great part of the public, are not totally fair in their evaluations.
Particularly, I can honestly say, that the BL industry is successful only with fanservice, ships and hot scenes, because it seems that many consider the chemistry between the characters only in these moments, and do not consider the plot itself, because most BL Dramas, can be considered toxic, there are only a few that really have a good story and are worth it.
I believe that the overall rating should be considered for the overall performance, taking into consideration the plot, and the acting of the entire cast, not just your favorite actors. I confess, if I were to consider only my favorite actors, my feedback would be much more positive and my ratings would be much higher. But actually, from my observation, considering the ratings, people only support ships and their favorite actors.
