Mr. Plankton (2024)

Nobody loves Hae Jo, because nobody, including Hae Jo, knows who is his real father. This makes people think he is like an impure substance among them. One day, he hears news that will change his life. He decides to go look for his real father. He happens to have Jo Jae Mi accompany him on his journey. Jo Jae Mi always wanted to have a family. She is going to marry Eo Heung, who is the successor in the Eo Family. The Eo family, including their mother Beom Ho Ja, run a food company. They don't like Jo Jae Mi as Eo Heung's wife, but accept her because Eo Heung told them that she is pregnant. On the day of their wedding and before the wedding ceremony starts, Jo Jae Mi disappears with Hae Jo. (Source: AsianWiki)
