This is a remake of the original hit Taiwanese movie. The Korean film has a university setting, whereas the original was set in high school, but the plot is similar other than that, with minor changes and tweaks.

Both feel nostalgic and have a portion that is set in high school, but they deal with more serious topics and coming-of-age elements such as first love, friendships and student life. High school sports are also in both, with fencing in Twenty-Five Twenty-One and swimming in Lovely Runner. OSTs also have very similar vibes.

Based on the world of sports, both dramas show struggling athletes/teams on the verge of giving up or retiring but then a new manager shows up and shakes things up for the best.

The female leads in both dramas time travel: in Splash Splash LOVE, the Female Lead time travels to Joseon, whereas in The Story of Park's Marriage Contract, the Female Lead travels from Joseon to present-day Seoul, South Korea. Both dramas have elements of historical and modern blended harmoniously together, without being too draggy and monotonous. The romance is sweet and the fantasy elements also do not disappoint.

The male leads in both the Korean drama and the Chinese movie are cats with ability to turn into a human and heal people around them in one way or another. They both live with strong and confident minded women that never cease to follow their dreams and make them come true. “Meow, the Secret Boy” is a very healing drama and I’m sure that people that liked it will definitely like the Chinese movie too, since they share the same concept.
