Both dramas have a Successful Career Woman hires a handsome boy for a party.
Romance. Upbeat stories

Similar Supernatural Story. A chance to change for the better for the selfish protagonist.
A bit more character driven to be honest

The same Friends to lovers trope but a more mature story. It is only a special so it never drags.
Short and sweet

Both stories are laid back and focuses on real-life issues without being over the top about it. Both male leads could be considered losers who tried to change
Both female leads are self centered but that flaw makes them real and easy to connect with emotionally

Similar plot line with a career woman with fertility issues and multiple suitors

Similar story just that A Perfect Match is older, well much older.

Similar scenario. Perfect Match came to mind when I saw the synopsis

Similar stories especially the tomboy female leads. There both leave an impression on you.

Same sibling like relationship with the leads with the added bonus of time travel in Love,Timeless

Friends falling in love.Love,Timeless only flaw is not enough focus on the two leads towards the end but that is not a problem in In Time With You

Both look at a couple divorcing with unexpected consequences. Narita Rikon is more slapstick and retro but it still has a lot of heart

Similar premise with roles reversed. I think Whos The One is more suitable for guys
