All in all enjoyable, but there were definitely some things I didn't like about it. It's only 6 episodes, but the episodes are relatively long, so that's not what bothered me.

My problem with this drama lies with the two main characters. Valen's lack of proper communication drives me nuts, but I think that's a personal thing. It makes sense with his backstory, which we pretty much have to figure out for ourselves. I feel for him, but even after it's clear--to him at least--that he really likes Kaitoon, he has a weird way of showing it most of the time and isn't doing himself any favors if he wants to win Kaitoon over. (Doing something really sweet for the guy you like? Tell him it was your sister's idea. Want to take him someplace special? Don't let him know what's going on even after you get there--Valen's lack of communication reminds me of my husband, and that's not a good thing.)
As for Kaitoon, he's mostly likeable. More at first than later. He can be forthright to the point of rudeness, and at first I thought maybe this was the kick in the butt Valen needed, but later on it seemed too brutal. (Did he really have to point out to Valen that some of the bracelets were done incorrectly after Valen helped him out with them?) I'm assuming Kaitoon has so much on his mind with school, his job, and his bracelet business that this is the reason he forgets something important. Twice. But nothing is actually SAID about that being the reason. I'm not even sure if he likes Valen, to be honest.
As for the secondary characters, Nont is great, but he's wasted in his role forming a weak love triangle with Kaitoon and Valen (because who knows if Kaitoon likes Nont), but we don't know enough about him to feel anything but sorry for him in the last little bit of the show when we finally get an idea he has feelings for Nont.
King and Peat's story started out interesting but then became weak when it became apparent King is no longer feeling it. Enter a young guy who suddenly becomes a model for King's art and more confusion ensues.
While it was nice to see Jeff Satur again (Marwin from Ingredients), his role is useless in the story. I don't know if he's supposed to be interested in Kaitoon or what, and isn't that what Nont is for? Maybe in season 2 he'll get with the male model, or with Peat if King winds up dumping him. Then there's the odd guy who keeps flirting with Valen's sister, Pang. This is just unnecessary extra stuff that could have been used for other things, like plot.
The story jumps around too much. I'm sure the point of having Valen act in a play is so that Kaitoon can help him through it, but what about the EXTREMELY long wait before he delivers his last line? So weird and unnecessary. It wasted moments that could have been used for, let's say, character development.
And the swim club? Purpose? We never see anyone swimming. I thought maybe the club would be a way to get Kaitoon and Valen closer but nope.
So, in my opinion, not a total waste of time, but not worth a rewatch. The season 2 trailer of a Valen/Kaitoon love scene shows a moment of chemistry. Which gives me hope, I guess.
