Both plots are heavily based on the time traveling concept and are definite melodramas. Although in Tomorrow With You the ML can control his time traveling while the leads in Someday or One Day could not, the yearning romance is still the same. Loved both!

Both have similar arranged marriage premises and are super cute. They both have a slice of life vibe and are adapted from mangas. However, Marry Me! is a lot less animated.

Both are cute web drama stories that are around 2 hours of sweetness. They both have supernatural plots that are well developed for a web drama.

The drama remake version of the same story. Although the actors are different, the storyline is exactly the same.

Both are romance movies that deal with wheel-chair bound disabilities. Both are bittersweet tearjerkers.

Both of these movies are set in the "Golden Age of Film" and the setting switches back and forth from the past to the present and vice versa (The Notebook style). But Forever Love is set in Taiwan. The lead males in both movies write scripts and are aspiring to be something greater.

Both are about college students falling in love. Both lead males are incredible good looking and female leads are both cute.

Both are centered around mermaids, the male leads have sketchy occupations, and there are interspecies romances.

[Spoiler Alert] I got the same feels at the ending with this one as I did with Uncontrollably Fond.
