During the final recording of the program The Seasons: Park Bo Gums Cantabile on KBS2 on July 22, Park Bo Gum was watching a video recorded in response to IUs message to her, when the female singer suddenly appeared.
She held a bouquet of flowers in her hand, stepped onto the stage and said: "I feel sorry for not being able to come... so I came by myself".
This unexpected moment moved Park Bo Gum. He stood up, Clapped because he was so shocked and wiped his tears. While the studio audience also cheered enthusiastically when they saw IU.
IU continued to melt the hearts of the audience by kneeling down to give Park Bo Gum the bouquet of flowers she brought, creating a romantic scene that quickly spread on social networks. Many netizens commented that IU's flower giving scene was like "marrying off with Park Bo Gum".
Others associate it with the two characters Ae Sun (IU) and Gwan Sik (Park Bo Gum) in Netflixs drama When Life Gives You Tangerines. They pointed out that IU's bold actions are very similar to Ae Sun's personality in the film.

Some other audiences said that they had predicted that IU would be a guest on the final episode of Park Bo Gum's "The Seasons", which will air on August 1.
Park Bo Gum shared that although he really wanted IU to be a guest on the show The Seasons and met IU at the recent Blue Dragon Television Awards, Bo Gum decided not to invite IU because he knew she was very busy with a new filming schedule.
However, IU took the initiative to surprise Park Bo Gum when appearing on set.
Park Bo Gum and IU's 13-year friendship is admired. The two first met when they worked together in an advertisement in 2012. Then, at the age of 20, Park Bo Gum had a special appearance in the TV series The Producers starring IU.
Because the two artists are of the same age (both born in 1993), they have maintained a close friendship until now.
IU once revealed that one of the reasons she decided to take the lead role in the drama When Life Is for You was because she knew Park Bo Gum would be her co-star.
As I remember it, when I first heard that Bo Gum was chosen to play Gwan Sik, the first thing that came out of my mouth was: Is it okay for him to be so handsome? Is it okay for the character Gwan Sik to look like that?
Because if he were that handsome, I'm sure everyone on the island would probably love him, and I didn't think he could stay on the island," the singer said.
In response, Park Bo Gum also expressed his excitement at knowing IU would play the female lead: "For me, too, when I heard about casting, IU was someone I wanted to work with for a long time as an actress and an artist."
