You Are So Sweet (2020)

-There is a female that likes ML for a long time, is business partner, tries to sabotage relationship of FL & ML
-CEO & secretary relationship, more bubbly FL
-SML is "friends" with CEO and likes FL (at least in the beginning)
- You Are So Sweet is waaaaay more light hearted

- Innocent but not naive FL
- A ML with slight prejudice against the FL at first impression
- ML has a friend that gives him advice or pushes him
- Second female is a successful woman that has liked ML for a long time and plots things against the FL

Female lead is cute and hardworking.
Male lead is dominering CEO-type (he works in dubbing)
There is a secret between them.
Better ML/FL chemistry
Both FL and ML has a quirky best friend
Those quirky friends become a couple too.
Happy ending

This has a really funny pineapple montage scene that I can't get over.

Hidden/Double Identity
Boss/Employee Lord/Maid relationship
Multiple couples
Both sweet as sugar (Xia Ge)
Fangirl /Idol

The FL has a passion for dubbing (not singing)
She is cute and hardworking

The ML is a bit arrogant CEO-type with a heart of gold
He has a secret identity

The FL struggle to enter the industry and the two fall for each other.
There is also some funny moments with the second leads. It is sweet, funny and charming.
I would argue that it is better than "My Special Girl".
