My Unfortunate Boyfriend (2015)

-Both have kind and innocent MLs
-Both dramas are light and fluffy for most part
-Both somewhat follow theme of hidden identity
-Main contrast is the FL's in both dramas have different responses to their ML's innocence

-Ultimately if you're looking to watch something with a palate-cleansing quality then MUB is a good watch for giggles and sweet romance

Both have a cute and innocent male lead and good comedy. The story lines are different though. I liked SKL better but both worth to be watched and are good dramas.

both have nice/innocent male leads and have prickly/bossy female leads.

-Both have male leads with (possible) mental problems/ naive /childish behavior
-Both male leads are flower deliverers
MUB is much sweeter and has much more comedy in fluff in it.

Similar sense of silly humor in both dramas. The OTP/main leads of MyUnfortunateBoyfriend put in embarrasing situations, meanwhile ALL the cast of Rak Ork Akard (including the OTP at the start) bicker in similar fashion to the OTP of MyUnfortunateBoyfriend.

Also both have a male and female lead from two different worlds who have to overcome their differences.

The male leads in both drama are cute & innocent type and female leads are headstrong.MUB is sweeter and lighter romance whilst HGL deals with serious problems rooted in Korean society.
