When I first started watching ATOTS, I had no idea that it was Mix's FIRST BL!! His acting was just amazing, everything from tears to laughter to anger felt so real and it really makes you forget that this is a series?(one of the reasons i cried so much watching this was because of this man's ability to portray Tian's sadness with micro expressions, like holding in his tears, he did it so well) . And Earth was great too! I think he played the "cold man soft heart" character pretty well as he knows how to get his deliver them without being too unnatural.
10/10 for acting

Plot
I personally love the plot although i know some people might find what happened it episode 7-9 to be annoying, in the end I've just come to terms with it. (spoiler) I would see why the villagers were mad since Tian didn't really give them any other explanation besides "Miss Torfun is dead, and I'm responsible" LIKE NO YOURE NOT??? I know that it was just his survivor's guilt letting out what he's been keeping to himself this whole time but I think it contributes to the way the villagers reacted. The forest rangers on the other hand, W.T.F. bunch of cowards?. Especially for Phupha, he uses the excuse of embarrassing him in front of the whole village just to "get him back home safe" and make Tian hate him. Hello??? Have you seen the way Tian was so kind to everyone in the village?? WHAT makes you think he won't understand if you nicely told him to go back?. Even if he doesn't, at least you tried. People really need to stop making decisions for my man Tian, he needs therapy ASAP.
Would also like to touch on Tian(Mix)'s character development like I'm pretty sure he has the best one yet. From rich brat (not like he had any other choice) to a volunteer teacher who tries his best to do anything he can to help the villagers is SO F*CKING HEARTWARMING I feel so happy everytime I think about it. After the heart transplant he really wanted to change his life and live for the better, and I respect him for that. He had everything he needed and had the ability to just stay home and recover but no, he went to a rural village and lived there for a couple months to complete some "unfinished business" of Torfun's, which I think he wasn't even responsible for but oh well, if it makes him feel better. And his chemistry with everyone in the village?? I can see why everyone loves him including the elders. And his bond with the students is undeniable, saddest scene was when he had to leave the village and say their goodbyes
100/10 should watch for Tian and his students<3

MUSIC
I have no words for the music in this series. Not sure if I'm overreacting but the songs are so good that i can't help but shed a tear everytime i play them. From the OST to Lom by Num Kala, exquisite.(or maybe im just an easy crier idk?) But the way the lyrics are written and how well they fit in the series really makes it even more special. 100/10 for music

Rewatch value
I would definitely rewatch this again after some time, I've just finished this a few days ago but the urge to rewatch it is already kicking in. Will probably watch Cupid's Last Wish before rewatching this! But would definitely rewatch for the tears and the feels.
9/10

10/10 series with just a little bit of flaw, but that's probably just how life is. Also forgot to mention how after everyone episode ends, they give you a meaningful quote from the episode, so good.
