10 dramas/movies where characters, preferably the leads, were enemies/rivals in high school/childhood but became friends or lovers in adulthood.

1. Bad Buddy - lol I think I have an image or GIF that actually tracks this progression 


5.  Our Beloved Summer

7. Legally Romance

8. Love is sweet 

10 drama/movies where a lead with a disability hides the disability from others.

Does this count?

1. I am not a robot - ML is allergic to humans

Also do you guys remember if the ML from 'Lovers of the Red Sky' hid that he was blind? 

1. Where Stars Land - any more and it is spoilers.

2. The Beauty Inside

 Mmopus:
1. I am not a robot

I'm going to say no to this one because if I remember right, he kind of stayed in his house most of the time. I'm looking for ones where they actually go out and often interact with others but still keep their disability hidden.

As for Lovers of the Red Sky, I don't think he kept the fact that he was blind a secret. But I'm also not 100% sure if I remember right.

3.  Silent - ML hides his hearing loss

4. Dear Hyeri - hides her multiple personality disorder
