Both MLs have the superhuman ability to convert to an animal and the FL is the key to ending their plight

Both are bromance/Bl themed dramas with one of the lead character being a cop and the other a doctor.

Both are 2021 modern fantasy Chinese dramas involving four handsome mysterious guys and the female lead(s). In Love crossed hey are named 'Love Boys' and in FILWH, they are called Mr Time.

Both these dramas have the same feel. The story telling is similar with calm peaceful almost naive leads

The FLs in both dramas gave me the impression of ruthless to the point that they would go to any lengths to win.

Both these dramas tell the story of the relationship between the ML and the FL in online and real life. It is the ML who discovers their online friendships first after making issues for the FL offline and then try to make up for it.

Similar story line. FL , although likes ML, gets married to the King and sacrifices her love for the nation while the ML always supports her. so close yet so far.

The FLs in these stories share the same profession of being urologist. In Love clinic the ML is also a doctor but the ML in the 'You raise me up' is a patient bit both of them have same physical issues

The main leads in both these dramas face the same issue and forms a big part of the story. Kakafukaka is about a girl meeting her ex at a shared house while the lead in the kdrama goes to the doctor who is his ex-gf

The ML tries to get close to FL for stealing the research but unknowingly gets close to her. Does he betray, if yes how get gets back his lady love forms the rest of the story

Both of these Japanese dramas tell the stories of a group of people who are living in the same house.

ML collaborates with missing/dead younger brother's romantic partner. In "Kiken.." he partners up to find his missing half brother.
