It's a fact known to everyone who watches BL that Thai BL are quantity over quality, they produce a thousand show per year and you can barely find a bunch of them to be good or watchable.

First, I have to point out that the story is different from what's written in the synopsis here, there is no pranks or childish behaviour anywhere, there is only a senior who is at odds with his junior and he picks on him sometimes, that's it.

This series is one of the few that you simply don't watch it for the story or acting, but only if you are looking for a specific thing this drama has.
It's very light, not serious, erotic, and I dare say romantic (sort of), a red flag with questionable ideas type of romance but a romantic nonetheless.
Long story short, you watch it for the s*x scenes or to enjoy the pretty faces of the cast or watch it while doing anything to pass time, or simply you have too much time on your hands

Acting was barely acceptable, some characters had potential and room for improvement, story nonexistent, the idea is very simple however ~
There is nothing to write home about, except it is watchable not terrible that you'd drop it, but keep your expectations low, very low and you will be fine ~~
