Okay, you have to know one thing about me: I am a very picky BL-Drama-Lover. A drama has to be very well done for me to enjoy it. And Sotus definitely is one of those pretty much perfect done series!

But let me review it from the start. The storyline. I actually watched Sotus rather reductantly, because I didn't really like the trailer. But when I started watching it, I got into it more and more. The story starts out like any highschool-love-comedy-show: it is light-hearted, the characters are introduced and there isn't going on much in the first episode. But the story develops really lovely! The main couple (I'm sorry, I'm a Swiss loser, I cannot remember all the names) has this kind of rivalry-but-somehow-sexual-tension-dynamic I really love! Especially Artith seems to be so harsh and unapproachable. But that's what makes it interesting. As a viewer, you can follow the storyline, you get to know so many different characters and you also can observe how the relationship between the characters change.
It's not a sudden "oh, it's love at first sight and we're gonna fuck in the next episode", but it's... so sweet. It's slow-built, but it also satisfies us with a bit of fanservice, but most importantly, the development in the relationships - whether it's in a friendship-kind-of-way or in a romantic-kind-of-way - is really portrayed realistically. What I also appreciate, is that Artith doesn't fall in love at first sight, that he struggles with his own feelings and his sexuality. This is a big topic, as Asia isn't that progressive yet (compared to Europe, at least).
Also, there actually IS a story to follow, not only about the relationship between two guys, but also about their life in university and friendship!
Also, it kind of introduces us into the world of Asian universities and culture. Everyone living in the West would agree with me - it's very different from our traditions and habits.

And now let me start on the characters! Oh, they are played so well, you won't believe it until you see it. All the characters (not only the main ones) are chosen carefully (at least it seems like it), and they play their roles so perfectly! All of the actors have got talent, you can feel it. Their facial expressions are gold, their voices sound like honey, and their gestures fit into their roles.

I really recommend this series, if you're into angsty teenager love, discovering about sexuality, but in a sweet and cute way.
