This series contains so many typical BL elements - jealously, hidden feelings for each other, missing each other when they are gone - but since it's a Chinese production, it won't be a full blown BL but like I said, it's the closest you can get to an actual BL drama already.

Honestly the plot is really quite typical of any BL dramas/novels, you get a cold and quiet main character (MC) and then suddenly an active, extra-friendly person turns up in MC's life and everything changes. Then eventually they fall for each other and voila!

This series actually reminds me of HIStory 2: Crossing the Line since it revolves around sports and then like how the MC is good in the sport but due to some reason or another, doesn't perform as well anymore. Then the second MC turns up and changes his life around.

This Chinese series however, talks about how MC's father hired a fake brother for him so as to make his son overcome his psychological issues. Yet this fake brother is of a personality that is polar opposite to his son's and things start to get interesting from then on.

In my opinion, I always like dramas that at first involve a cold and quiet MC then because of someone's appearance he changes to become a much better person and falls in love with the 'someone'. You may dislike China's censorship laws but please do not dislike productions from their country. This is really a sweet series that I recommend everyone to watch!

Like many people in the comments mentioned, China has a very good potential to produce really fantastic BL dramas/movies should the law be not there and this series really just shows that.
