I watched the first couple of episodes with a sort of distance. I saw all the faults (the acting, the badly done dubbing, ... as often in the Chinese series ...). But little by little I let myself be taken in by this beautiful love story. This series is very short (five episodes) and therefore there is no room for secondary stories. Everything focuses on the couple Cheng Yi - Ling Zi Ming. Their story is a classic teenager/highschooler story. Childhood friends, broken families. They built themselves. Inseparable friends, impervious to the amorous convolutions that swirl around one or the other (that poor Lu Xiang Lin who does everything to show his love to Ling Zi Ming who does not see him, as if he were literally transparent and who endures snub after snub).
And we come to the last two episodes which are poignant, with a very beautiful and poetic dialogue. Cheng Yi who explains to Ling Zi Ming that their love is governed by gravity: they are irresistibly attracted to each other. Dubbing becomes a kind of voiceover. It's very moving and dignified at the same time.
