It is simply beautiful, I don't even have enough words to express my feelings towards this series. The story is on point, the music is wonderful, and the acting extraordinary. I'm not exaggerating, but the acting and the chemistry b/w the characters is pleasing to watch, they did a good job in capturing the emotions in a such a way that you'd literally melt. Such a heartwarming and eye-capturing series, I'd rewatch it like who know how many times. Each and every single actor in the series did an excellent job showing us various sides of a person be it the stubborn Tang Yi or the relentless Shao Fei, the innocent Zhao Zi. or the cool Jack (I can keep on going with every single character) and beautifully showed their other side of insecurity, loneliness, anxiety, etc. I'd give a whole galaxy to HIStory for giving this wonderful series to us, and a special thanks to all the people who worked to give us such an amazing series. HIStory 3 has crossed their own history of giving us some amazing BL series out there after HIStory 1 & 2.
P.S - If you want more interactions between the main characters, their off screen videos are awesome. Do check it out, you won't be disappointed.
