Both are movies depicting two high school girls falling in love with eachother. They were directed by the same person and take place in the phillipines.

Both are korean bl-dramas, in which the characters meet again after something happened in their high school days and hidden romantic feelings resurface.

Both follow an adult friend group managing love, sexuality, relationships and break up, work. The main male lead in both happens to be gay, owns some kind of internet blog and is romantically involved with a younger guy. Theres also a w/w relationship.
Both shows have romantic, comedic elements and a bright, diverse, funny cast of characters. However, both series can get pretty dramatic snd tragic...
Some actors appear in both shows as well, most prominently petch as his characters gets lots of screentime in wake up ladies 2.
I think its possible to jump into both second seasons blind, as time has progressed since the first season.

Both are sad romance short movies in which time plays a role, in the library theres alot of focus on time progression and in love buzz the male lead travels back in time. The twists in both are quite similar too.

Both are thai short films with i assume the same team and director. One character even appears in both. Both stories have funny but also sad, even tragic elements and a very similar vibe and atmosphere on top of having romance elements. Both feature a child character too.

The main characters connect over and because of a movie script, as at least one of the characters is a screenwriter. These stories are also realised, theres a movie within a movie structure. Romantic tension comes up. The characters also have to care for family and partners, which prevents some of the romance from blossoming..
Both films appear to be simple romcoms but theres a deeper layer to them. They genuinely made me cry like woah....

Both are movies by the same director. Theyre primarily comedies. In both the fourth wall is broken sometimes and theres a Wong Kar-Wai refrence in both, although you have to be familiar with his style to catch it in Fast and Feel Love.

Both are comedy films in which a character leaves another while having been with them for a long time but has to teach them basic human tasks before. They also share the same director.

Both movies focus on multiple characters and multiple storylines, primarily romance story lines, and are easy and quick watches without much deeper meaning or thought. They give off the same vibe.

Both are romance movies focusing on a relationship between two women. Theres a focus on family relations too.

Both are taiwanese movies in which two young women develop a bond as they share the same work. Other than that rene liu stars in both movies and theyre both kind of slice of life romance stories.

Both feature a male lead that travels back to the past and ends up being involved in a romance story. He supposedly comes to kickstart the romance between his parents (theres more to love buzz however...)
