On social networks, a series of posts reporting that Yoo Yeon Seok and Chae Soo Bin are dating caused a stir. An audience member even shared a photo that was said to be a handwritten letter publicly revealing the actor's love story.
Many fan-made news sites also posted information that the star couple of the movie "When the Phone Rings" fell in love after the movie finished filming.
However, this was just a joke on April 1 Fish Day by a group of fans who loved the two actors. They are looking forward to Yoo Yeon Seok and Chae Soo Bin filming a fake love story, following the couple's activities in recent times.
Similarly, many Korean celebrity couples were also rumored to be dating on April 1.
An audience surprised everyone when it was announced that Park Hyung Sik and Hong Hwa Yeon were dating, and the actress was even pregnant with her first child.
The two acted together in the movie "Buried Heart", bringing tears to the audience because of their harsh, cruel love story. The chemistry between Park Hyung Sik and his co-star was harmonious and was supported by the audience.
The couple from the movie "Love Next Door" Jung Hae In and Jung So Min also "shocked" fans because the dating news appeared all over social networks.
The two actors were suspected of dating from the time the show aired until the end. Previously, when asked about love rumors, Jung Hae In refused to answer. He was worried that everything he said could be distorted through the media.
After that, Jung So Min clarified in an interview that the dating rumors were untrue, but she did not feel awkward when hearing these rumors.
However, the fact that Jung Hae In and Jung So Min still maintained a close relationship after the show ended has made fans continue to hope that they will become a couple, like Hyun Bin and Son Ye Jin in Crash Landing on You.
Many other star couples such as Lee Sung Kyung - Ahn Hyo Seop, Kim Ji Won - Son Seok Koo were also paired up by the audience and released dating news on April Fish Day.

In the history of Korean showbiz, there are very few couples who were "exposed" for dating on April 1. Because the audience is skeptical and does not believe the information published on the Day of the Fourth Fish - which is the day when people can lie.
On April 1, 2016, Dispatch released a series of photos proving Kai and Krystal are dating. At first, many viewers did not believe it, but later, Kai and Krystal's company confirmed the relationship.
They were once a famous handsome couple in Korean showbiz. However, SM Entertainment said Kai and Krystal broke up after 1 year and 1 month of dating due to busy schedules.
