In both series the man is much younger than the woman and while the relationship starts as too people that make a sort of contract, they end up getting close to each other.

One is fantasy and the other not, but both are about the lonely FL discovering the ML who is injured, taking him home with her, and keeping him as her pet.

Both dramas are about a career woman...known to be tough & cold...is lost between the Sunbae she loved for a long time & the younger man who comes to live with her...Who will she choose in the end?

The main similarity is the on/off mode of our main character and their need to hide their insecurities and personality traits they think that contrast their "perfect" image(if you ask me everyone shows a different face depending on where they are anyway) . Another similarity is the sweet/demanding persona of the mls. Also both drama have a younger man/older woman romance.

I recommend this both drama because , Male lead and Female lead
try to solve problem
In one drama explosion and another student murder/suicide

Both are about a hard working woman that finds a boy in weird circumstances, takes him in and treats him as a pet, but due time becomes addicted to him and sees him as a man.

Shitara, a man who fell from his elite life overnight. His new "place of employment", which has lost his job, house, and wife, is a boarding house?! Under one roof, a perverted love begins from the worst encounter with one of those living there!

Both female protagonists of this drama are older than their male lovers. In both dramas there are scenes of coexistence between the protagonists.

Both drama deal with age difference in relationships (older woman-younger man) and the topic of whether one should conform to society's expectations or not. Strong 2nd lead presence too.

Both deal with a Ms Perfect learning to drop her guard and fall in love with someone they didn't intend on loving!

Both drama serve as the female lead's "dog."

Kono Otoko is more of a comedy while Kimi wa Petto is surprisingly grounded.

KWP doesn’t have explicit BDSM the way Love and Leashes does, but the aspect of dog role play and the relationship between the fl and ml is definitely a DS one. Both also delve into how engaging in DS helps relieve stress and anxiety for both parties in different ways.
