Some fucked up part of me is just saying "Now this. Is the ultimate revenge." Cuz think about it.
Yeonwoo had to deal with his toxic ass for a majority of the manhwa, even having to have his child and the one thing Keith, the one excuse he kept on repeating is that he "marked" him on purpose.
So when Yeonwoo said his mark will be gone and we get to see the flashbacks, you see Keith just crumbling into a pile of emotions.
And remember how Yeonwoo said he wanted revenge? Well, Keith is used to having what he wants given to him when he wants and the one thing he wants is slowly drifting away along with his unborn child.
Its the ultimate revenge because he never got what he wanted in the end.
its always the blondes that cause the trouble
