I want to read more about why the secretary fell for the blonde this much

The story of them hasn’t been written much. We know they have a bit of chemistry but I still cannot see how it developed into his current feelings. Like what makes him so devoted he almost put everything in his life for his one-sided love. Just one episode of how they met is not enough, but I have faith in the author so I’ll patiently wait and see how their story’s gonna go.
