I got scandalised by what was written from someone below so decided to do a little research on the novel.
The spoilers are false.
SPOILER!!!
From what I read on novel updates, ML actively pursues FL and she accepts his advances. They start dating in secret and only make their relationship public when they announce their marriage. Most of ML's family treat FL well and there isn't major drama about her not being a chaebol. FL continues to work in the company along with ML after they get married and they have a son which resembles ML. All in all it is a stereotypical romance comedy webtoon.
This is where I read the spoilers from: https://www.novelupdatesforum.com/threads/lee-seob%E2%80%99s-love.172155/
