Comfy romcom with "Secret Relationship"

Looking for comfy romcom with "Secret Relationship" like Hit the Top, Fight for My Way, Romance Is a Bonus Book, backstreet rookie.

Must have happy ending.

Not looking for cheating, time skip or shows with letterboxing (black bars at the top and bottom portions of the frame)

Thanks

For Chinese dramas:
Go Go Squid - this is a mixture of fake dating and actually secretly dating. Its very sweet.
Perfect and Casual - this is kinda similar to Romance is a Bonus Book
Somewhere only we know - Student/Teacher romance story
Something just like this - kinda step sibling romance? I dunno how to call it. She was raised by his family
Lost Romance - so this here is with them being enemies and her being his subordinate. Thing happen and she kinda ends up living with him.
Find Yourself - she is his boss and also a few years older.


Kdramas:
Secret Romance - as the title says. Secret relationship. But there is a time skip from them meeting to them meeting again. However  it is only one episode that is in the past and the majority takes place in the "now".
Her Private Life  - work colleagues that end up dating
Something in the Rain - family friends, and she is his sisters best friend.  this has some great romance scenes but the fm's mother is quite annoying.
Because this is my first life
what's wrong with secretary Kim - work colleagues

Time to fall in love
