The author needs to write Dohwan chasing Yoon Sang later. I know YS agreed to the “light/casual” relationship, but if you know the other person is serious about you, just reject them outright. That's what a decent person would do.

If you meet someone like Dohwan in real life and you're like YS, just let it go. You'll only get heartbroken. The chances of them changing like they do in fictional stories are slim. Don't fall in love with someone's potential. Fall in love with who they are and how they treat you now.
