I have watched many Thai dramas before, just in general. And I have watched a decent amount of Thai BL dramas as well. This show is so much different than theirs.

CINEMATOGRAPHY:
I would love to comment on the cinematography, it was literally perfect and beautiful, I specifically love the confession scene with the hammock. The blue background with the beach just seem so peaceful like the only thing that was there was them 2. No one else existed. And that is what they were kind of saying in the scene as well. "I want to be the closest to you, no one else" (not an actual quote, but similar).
PACING:
The pacing is what makes it so much different from other Thai shows I feel like. Other series kinda make it a lot more fast-paced and keep it moving. For a 5 episodes series them being 1 hour long, I did not feel rushed or pushed like I normally do. The storyline was played out really well and very distributed between the enemies to friends to lovers. You could see the transition between each of the stages and I felt like it was just perfect and done really well. It almost felt slow, but wasn't and I think in those "slow" scenes they truly utilize the silence and the eyes and stares it was perfect.
STORYLINE & ACTING:
What also made it different is that it's a lot more light, And I think for the storyline the way the cinematography and the pacing were done just match the storyline. I am a sucker for like classmate love so when I found that out I just loved it. The silences and stares between Oh and Teh displayed so much tension and we, the audience, notice so much history in the beginning and created enough romance just from that. Along with that, I love the small parallels, the back-scratching to THAT SCENE ;) and the knees touching, it just represented so much I felt like. However I do agree with some of the other watchers that Teh constant crying was a bit overused I understand the pressure, heartbreak, etc. That he deals with, but still... I am sure that Teh's character is made to make us mad, which it did, constantly, the fact that he lead on Oh and Tarn was so upsetting for me, and made me make it through the day I watched it. The fact that Oh also constantly went back, I do love the fact that Oh and Bas did have a moment together where they did end up together and the fact that Bas let it happen and realized it is love in itself.
MUSIC:
GOD the music intensify my emotions so much, it made me feel everything times 100 it was literally perfect. the music use was used really well.

*thumbs up* i would recommend for a filler drama, or like a break drama tbh.
