One of the characters speaks another language and the leads go from enemies to lovers. One of the characters is somewhat childish, energetic and has a crush on another girl, but ends up falling for the other lead. The other lead has a secret crush.

Similar feeling, Thai BL romcom. One childish male lead who's in love with a celebrity and has an overbearing older brother. Ends up falling for another man.

Another bl rom com from Thailand where the two leads don't get along at first and fight with each other.

Another bl where one lead seems to be bully and the other bullied. They don't seem to get along at first but in end in love at the end.

In both, one lead has a crush on the other but they have a rivalry relationship that makes it hard to act on it. Similar dynamics.

Both are Japanese bl between a cool character that is looked up to and an awkward character. Both relationships develop slowly and have an awkwardness about them.
