Not really a love story is about ML a Japanese man & FL a Hong Kong woman living in an island of the last fishing village in Hong Kong. A bit confusing, weird & unique story. I need more Japanese Hong Kong movie or drama collaboration. Odagiri Joe is a versatile & has a unique charm actor.

Both dramas have a character of a Fujoshi girl who writes a fiction about boys she knows and her ship(s) eventually become(s) real.
Both shows are funny and entertaining but also can make you cry at certain moments.

boss & secretary relationship that begins with lots of fight and bickering and end up being lovey-dovey couple

The general feel of the shows is very similar, firstly. It's centered around a lot of growth, and explores friendships and relationships.
The leads in both the shows have dreams that they are chasing, and they are trying to navigate their relationship along with them.
SPOILER:
The largest similarity, however, is in their endings. They separate because their timings were wrong, and they were at stages in their lives, where it was just not possible to be together, if they also wanted to follow their own paths. And so they separate. But both endings are ambiguous, and give us hope, that one day, when the time is right, they might reunite.
And I truly appreciate these endings. They're very realistic.

Both male leads are heirs to a traditional business that involves wearing traditional style of clothing. Both have a psycho female character pulling the strings. Both female leads have to navigate working the ins and outs of the business. Promise Cinderella is more of a romantic comedy while Watashitachi wa Douka Shiteiru is a little bit more of darker revenge.

Both these drama centre around a group of women in their "club". Ex-girlfriend club focuses on four women who all have anger towards their shared ex. Meanwhile, green Mother's Club shows the different dynamics in relationships between mothers whose children all attend the same school.

Both dramas contain characters which work within a school environment. Whilst love with flaws is more lightheaded being a romantic comedy, black dog is more serious in detecting the issues faced within schools.

Both of these are work based dramas which show the struggles of the lead as they work within a temporary placement. In black dog it is a case of the FL being a temporary teacher whilst in kkondae intern, the second ML works temporarily due to being on an internship.
