Lucky Romance (2016)

Both dramas have cold, brilliant male leads working on IT company, living an unsocial life and disliking romantic relationship (both for different reason).

Both these romcoms have a female lead whose different, quirky and bizzare. Oh Hae Young is perhaps more impulsive. Both females find themselves blurting amuzing embarassing things or situations. Both males are closed off and cold, seldom smile and even socially inept. Jo Se Ho in lucky romance is also bit nerdy and has an additional dimension in his character that really draws you in. Both become unwillingly drawn to the female lead and behave out of character.
Both dramas have poor first episode but gets better. The good acting and interactions compels you to follow their story.

-For some circumstances both female leads want to spend a night with the male lead.

-Both have a superstitious element.

I have not watched "Lucky Club", but by reading the synopsis, it reminded me a lot of "Lucky Romance".
In both shows we have a superstitious female lead who falls for the smart, genius and down on earth type guy.
I like a lot of this drama, "Lucky Romance" and I just discover and added "Lucky Club" on my plan to watch list.
Maybe I get back and write more about both shows similarities after watching "Lucky Club" .

- male leads are CEO of a company
- rich male lead paired with an ordinary female lead
- male leads fall in love with the quirky female lead
- light and fluffy romcom
- pushy second male lead and second female lead (the third person in the leads relationship)

In Lucky Romance the fl is convinced she brings bad luck to people and wants to stay away from others/the people she cares about as a result.

In I'm not a Robot the ml believes he is allergic to people and has built his entire life around never touching another human being.

Though these are obviously different, I found the concepts similar and the general feeling when watching was also quite alike. Both romances are very cutesy and brings a smile to your face.
