What's Wrong with Secretary Kim

A rom-com with a dark tone but also a romance drama where the new president of the company falls all over heels for his secretary. Also here it is the male lead who falls first and tries to win over her heart.

The dramas differ completely in terms of genre, so they give very diferent feelings (though you'll wanna hug the leads in both hehe), but they have some similar points (spoiler alert):
- A trauma in childhood that greatly affects the characters' adult life;
- Supportive families, but with some sibling (between brothers) issues;
- A solid, lovely main couple that isn't bothered by third parties. They meet when they're young, go their separe ways and only meet again as adults. They trust each other from the beginning until the ending.
