Grumpy Fake Boyfriend

The trope is so popular, but I wonder what the author thought about when putting their own spin on it. Did they have a particular message in mind?

The witty back-and-forth was fun, but I kept wondering if it was meant to highlight their chemistry or just to keep things light.

The blend of comedy and heartfelt scenes felt seamless, and I'm curious whether that was a deliberate choice or evolved naturally during writing.
