I only watched this because of Zhang Ling He because of his wonderful performance in 'Love between fairy and devil' and found another good drama.

Like other youth dramas, it uses the cold straight A student ML who loves a warm but not studious FL trope. Its notable difference in other youth dramas is the depiction of a differently abled person as an ML. So Jianghao's coldness is understandable. It came from his insecurities of having a father that is no good and having an artificial leg. He only trusts Lu Miao because as she's his childhood friend/almost sibling who never judged him. I loved how the drama showed that being differently abled has some advantages and was not a disadvantage to love at all. Another thing I learned was 5211314 is another way of saying 'I love you forever' because it sounds like "wu er yi" = "wo ai ni".
