Every modern rom-com cliche ... all in a comic, graphic novel type package

The plot covers two romances:

Plot A: the perfect billionaire grandson who falls for a pretty, silly and loveable girl from a humble background
Plot B: the rebellious billionaire daughter who falls for a serious, earnest, and secretly hot man with a bit of a past

The plots carries along with hijinks, and secrets, and slapstick humor. Never too stressful, serious, or well, unexpected.

Comparisons to Secretary Kim are inevitable. But in Secretary Kim, the power balance is much more subversive.

The acting is competent all around, but the chemistry between the two main leads was a bit lacking. Common for the genre, but they both were like two teenagers with a crush. The secondary romance was much more naturalistic and lived in, and they had good banter and physical chemistry. I enjoyed that romance a lot more.

Music didn't really register, no need to really rewatch. I grade on other criteria:

Complex Themes: 5
Follow your heart and be earnest and everything will work out. Lies are always found out.

Character Growth: 4
Really, none.

Interactions between Women: 6
The main female lead genuinely engages with her female coworkers about developing products and succeeding at their goals. While interactions with her mother and best friend are often centered around men, they are not always, and the main lead has plenty of screentime with other women.

Production values: 7.5
At this point, I expect more. While with a larger budget than dramas of 10 years ago, the clothing and style was a bit lackluster, as were the sets. There was little to no creativity attempted with the filming.
