The cdrama is the original version. was also made into drama before the Thai version. same story, characters.

The ml in this drama gives vibes of ml from WLFKBJ! Both ml's do swimming, one is in high school whilst the other is in uni.

The synopsis is similar. Both ml and fml in both dramas grow up together on a small island. Due to some issues, they go separate ways and dont meet for many years. They coincidently meet again after many years when one is having a hard time. They look after each other, become the sun, and overcome the issues.

It has the same love triangle. The poor friend likes the female lead first but the rich friend finds out and out of curiosity, he steals her. The plot and genre are different though,

Office romance. Employee and CEO romance. Enemies to lovers. ML is the son of a wealthy family. Poor woman/rich man.
