Both take place between co-workers in an office setting. Both BDSM, with a master-slave relationship story line. One adapted from a manga, and the other a webtoon.

Both are about a male lead who are obsessive in their love for the FL.
Also they are both pretty weird intelligent guys with glasses.

• Both dramas have a ML that are an overbearing CEO who manipulates and schemes to get the FL into a relationship with them.

• Rich Man and Poor Woman in both

• Boss/Employee

• The FL of both also have a short temper and despite their slight builds can be strong enough to take down grown men.

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

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

Yuino Sakura has always focused on her work, putting love on the back burner. When she transfers to her new workplace, she meets her perfect, handsome boss, Kiritani Itsuki. But Sakura has an extreme "smell fetish"... When she suddenly smells Kiritani's scent, she can't help but "fall in love at first sight"!?
On the other hand, Kiritani has become an "untouchable man" who is not used to women due to past trauma with women. Since the day these two awkward people find out each other's secrets, have they started to grow closer in both distance and heart...?

This office love story between two shy people in love begins with a frustrating and sweet "scent"!
