In my opinion this drama was just perfect! Of course this also has a lot to do with my preferences for BL stories and characters. Even though it's not perfectly obvious who is the seme and who is the uke in the main relationship (and it's also not necessary to know), I considered Xia Yu Hao as the uke, and I really like delinquent / rebel uke characters because they are usually so soft and loving once you get to know them better which really contrasts with the way they pretend to be. Also I love it when the seme character is a little tsundere and the uke is more active, so this couple was exactly to my liking^^
The actors also portrayed the characters extremely well. I was especially impressed with the actor playing Xia Yu Hao who really made me feel the emotions of the character and in addition is simply overwhelmingly cute and pretty! Qiu Zi Xuan's feelings and thoughts on the other hand were not so easy to understand, but that was part of his character who was more reserved and composed. Overall the actors were great and made the story so emotional and enjoyable to watch. The romantic scenes where in no way awkward, but seemed very natural and real.

Many people are complaining that this drama is too short, but in my opinon that is not the case. In comparison to many Thai dramas (of which I have seen a lot) that usually exaggerate with the time given to every single scene to really build up that emotion, I actually prefer this faster pacing of the HIStory Series. Making this series longer (without adding more story) wouldn't have made it better. For me the story is told just at the right speed to not make it seem rushed, but also not let it get boring. And the emotional / romantic scenes are still long and passionate enough to really get involved emotionally. (And if I wanted more I sometimes just watched single scenes on repeat^^)

Even though it was such a short series it also included a second couple that didn't get as much screentime, but still enough to make their story seem satisfyingly complete which I really appreciated. Here we had another active uke (although his confession was kind of unintentional), and I also have a thing for romantic relationships between brothers, so this story exactly suited my taste, too, which made the series even more perfect for me. All the important side characters were also smoothly included in the story and the relationships between the main characters and their respective friends were very beautiful and supporting.
Although I don't have anything to complain about, I gave "only" 9 stars for the story because I didn't feel like it was anything special enough to give it a 10/10. Overall though this series definitely deserves the 10 stars. I will surely watch it again and I can only recommend it to all of you :)
