Though both drama have different setup, But THE SUSPENSE part newer disappoints in both the dramas

Both stories involve a crown heir escaping to Thailand and disguising themselves as a commoner to survive. In Thailand, they learn to experience an ordinary life and fall in love.

Unstable young female characters able to go through great lengths for the one they love, if you may a sick love

They both start with the family husband being charged of murdering their family and chased by the police even though all the police has is circumstantial evidence.

Same director, so it creates a similar feel. If you laugh while watching What’s Wrong With Secretary Kim, Because This Is My First Life will make you laugh.
Both male leads don’t believe in love, but end up falling in love.
Funny important person giving advice to the male lead.
Same sound effects.

Both series have a fun and light hearted approach to gay relationships. Both are worth the watch, although the character dynamics are completely different.

They have a similar feel initially.. the storyline is completely different but a lot of things give a similar feeling for instance the fighting, gangs and the older woman who falls for the ML because he protects and cares for her, but i found the couple in 'only side by side with you' cuter than in K2.
