Un milliardaire sinon rien, tome 3

The humor feels so natural and not forced, which is rare in romantic comedies. I'm curious whether this was a deliberate choice or evolved during writing.

The banter and sparks between the leads are great, but sometimes it felt a little too idealized. Do others think that adds to the fun or takes away realism?

The descriptions of high-end boutiques and designer labels add such a vivid backdrop. I wonder if the author has personal experience or did extensive research to bring this to life.
