Although the setting is in no way similar because K2 is all about action and fighting scenes, the part about the male lead taking care of the female lead is the same. In Liar Game, the male lead takes care of the too-kind and naive girl through the entire drama. And even though there is not romance, there are little hints about a relationship between the MCs.

Childhood friends as a romance plot are great, but trying to be first in your craft and your biggest rival are your best friend(s)... that's it

FL are cheerful
There is also Teacher and student relationship but its more likely Senior and Junior relationship.
ML is the leader of Sect Tai Chi. And hes so strong. He helped FL to be more powerful.
There is another story with the grandparents in the past too.
