Recommendations

MLs - handsome, rich, arrogant CEOs
FLs - kind & cheerful girls from a poor family who is an employee of MLs.
Later they signed a contract to helping each other in different matters. Business Proposal is pure classic romcom. Master's Sun is also a romcom with horror elements. Both couples have very good chemistry.

the name Hiru means Leaches! both of these titles are about people who sneak into unoccupied rooms and live off other people. the themes "crime and death" are also shared

Both FL in movies knew they only have short time to life. They life until the fullest of their life. Both ML supported them until both FL last breath. A sad touching love story based on true story.

They have very similar vibes. I would say Sweet Teeth is executed better and they are inherently different, but that calming, beige-ridden, 2021 c drama vibe is the same.

First they are both really good dramas.
Second they both have female go back in time and meet male lead.
Third male lead gets bad luck in future so female lead returns to the past to fix it. (Don’t wanna spoil so won’t say exactly what happens)
Fourth both have really nice and protective made leads that protect the female lead in any situation.

Both of the protagonist talk by themselves. Bun (Hokusai to Meshi) talks with her stuffed toy named Hokusai while Mitsuko (Hold me Back) has "A" as her counselor.

Both comedies where the girl hides her identity from the guy and has a “disguise”. Guy takes awhile to figure out that the girl is the girl in disguise. Also, in both the girl works for the guy.

Reconciliating with favourite sport (basketball) after stepping away from it and facing the past. Romance born from shared passion.

It's also a drama based on family matters and the problems that arise in the family... It also depicts parental love, brotherhood, etc.

Both dramas have a poor female lead, rich male lead and a fake identity trope. The leads are in a contract relationship in order to fulfil the wish of the male lead's grandfather. In Business Proposal they are pretending to date whereas in My Girl they are pretending to be cousins.

They´re both soft in the storyline and also tend to be more comedy than drama. "Oh! Boarding house" sometimes seems like a parody of other BL series/ stories. I think both are equally light and fun to watch.

Both have an uncomplicated storyline and a similar production. However, "OH! Boarding house" is better in the implementation of the story. Way better. The love story of the main leads both evolves around adulthood. I´d recommend "Oh! Boarding house" even if you didn´t like "Behind Cut".

older women/younger man couple, boss/employee relationship, great chemistry. For me, The Rational Life is the perfect romance drama and for Why Women Love ending is so satisfying. I hope you enjoy the love and affection.
