First of all, Both give a similar vibe with how the character were written to be. Both shows plots are a ridiculously scenarios. Both shows main leads have to figure out how to coexist and eventually they find that they enjoy spending time together. I don't know if it's just me but I think since they both are from the same network company maybe writers or producers from one show worked on the other show, making them very alike.

Other Similarities:
Both Female Leads are strong, hardworking, quick witted women.
Both Male Leads are misunderstood in the beginning and overtime learn to be understood.
-It's still too early to say that the ML from wedding impossible is misunderstood but I think he acts out but he's intentions are different from what the FL sees.

Both Shows Plots are somewhat different but both FL have similar experiences. They both are surrounded by males who find her the FL interesting but not necessarily romantically. They have both feel in love for narcissistic, chaebol(Heir) and have live with th e difficulties of their families and their lifestyle.

More Similarites:
BOF has a somewhat tomboyish FL
They are the go-getter type
Both have experience with delivery services. ;)

Both Show are great in their own style but differently worth watching these classics.

Both originated from a Webtoon that has a Gumiho present. One that very obvious and another who isn't. In both drama the main lead(s) are/is trying to figure out a solution to accident they have created. (Spoiler Alert) Around the second half of the drama the female leads gets her memories erased and we see the ML struggle to get the girl to fall in love again. Do they succeeded? That's something you have to find out by watching both shows.

First of all, both Male leads are wealthy heirs to a big company. Second of all both female leads work very closely with the male leads. Both dramas have male leads who are narcissistic chaebols who suffer from the trauma of trusting people and both female leads are strong hard working trusting leads.

Other Similarities:
Both fit the poor woman, rich man trope.
Both Male leads start off badly with the female lead but end up falling first and harder.
Both aren't strict with just office/business settings.

Strong Woman Do Bong Soon is one of those "you must have watched" dramas that most people get into first. (Basically, a beginner drama most people have watched). It's also very unique from traditional office romances because of the crime and supernatural elements. It's one of those comfort dramas that leaves you with such incredible satisfaction.
