My first response to this series was: "Another tyrannical-boss-and-quirky-subordinate story?" The story relies on several familiar tropes, including a disapproving mother towards the end. Nonetheless, I did find it fairly watchable. It is rather stress-free watching because we more or less know how the story will develop and end. And the BL couple is fairly likable.

Be warned, however, that there are several poor transitional points. First of all, although we know that Xia Shangzhou (the tyrannical General Manager) takes a liking to his new secretary (Yao Shunyu), it strikes me as a little too sudden when Xia frantically rushes to the rescue of a kidnapped Yao. Clearly, there weren't enough scenes to show that Xia had already fallen so hard for Yao. Other poor transitions include Yao's own struggles with his own emotions. Yao goes through several stages:

1. he notices Xia's interest in him and freaks out;
2. he struggles with his own sexuality but eventually comes to terms with the fact that he is in love with a man;
3. he struggles with being uncertain if he is just a fling to Xia despite being in love with Xia and accepting it;
4. he realizes that Xia really loves him but decides not to accept Xia so that Xia can avoid being embroiled in a scandal.

Although things cannot possibly be entirely clear-cut, the shifts from one stage of Yao to another is a little too muddled to be truly moving.

Despite the flaws, I did enjoy some comic moments in the series. Unfortunately some of these moments also fall flat despite having potential. A case in point is when Yao is given the task of sabotaging Xia's blind date (arranged by Xia's mother). Somehow, Yao ends up buying a whole lot of condoms, causing the woman who was arranged to go on a date with Xia to think that Xia is a pervert. (Erm.... excuse me, first, Yao shouts to Xia "You are mine" but the woman mistakenly thinks that he is speaking to her. Then the condoms fall out ... and the woman thinks Xia is a pervert even though all Xia does is to help Yao, who is slipping. ????)

Somehow another Taiwanese BL, Stay by My Side, is listed as Related Content in MDL. I'm not sure about the links, but Stay by My Side is overall much better. Despite the cliches and predictability, I think You Are Mine had the potential to be much better than it has turned out to be. It is somewhat enjoyable, but nowadays, there are probably better BLs to watch.
