Made in Thailand, both of these series deal with a medical student and an engeneering student falling in love. There is friction, and the med student ends up catching the eye of yet another guy, making the engineering student jealous.
Both also have a token of love, if you will. In My Engineer, it's roses and other flowers they use to communicate their feelings. In My Gear And Your Gown they have a pair of earrings they share.

As they are both Chinese series, they have the language in common.
They also have a similar vibe, with the costumes being the same kind of fashion.

Just like Pornographer, Sei no Gekiyaku has some very mature contents. Both are made in Japan and concentrate on an LGBTQIA+ relationship. You could also (in my humble opinion) say that, in both Pornographer and SNG, one takes advantage of the other, leading to a physical relationship and feelings that begin to grow.

Both shows are absolutely gripping and showcase the growth of the unlikely friendship between a cold man and a female detective who knows how to hold her own. Both are trying to solve a case that leads back to corrupt politicians. If you enjoyed one, you'll definitely enjoy the other.

it has the same type or romantic comedy to it. the slight love triangle but no second lead syndrome (at least in my opinion). it also had rich family involved and also an underlying drama that became more prevalent later in the story.
