Lee Joon-ki's appearance at IU's concert sparked memories among netizens. What movies and TV series have the two collaborated on before?

Lee Jun-ki and IU have collaborated on a TV series before, called "Bu Bu Jing Xin: Li". This drama is an adaptation of the Chinese TV series "Bu Bu Jing Xin". The characters in the play are lovers, but they are separated because of their love. The details are as follows:

Firstly, Lee Joon-ki and IU collaborated on a TV series "Biao Bu Jing Xin: Li". This drama had a great influence at the time. After all, it was adapted from a Chinese hit. Red drama.

Lee Jun-ki and IU collaborated on the TV series "Step by Step: Rei". In this drama, IU played the role of Jieshu, a soul traveling through time. Lee Jun-ki played the role of the fourth prince Wang So. The two began to have feelings for each other because of some misunderstandings, but because the fourth prince fought for the kingship, many people died. After the fourth prince got the kingship, he eradicated those who were not good to him, which made Jie Shu helpless. Eventually, the two of them drifted apart and gradually separated. Although the plot was very sad, this drama made the two of them more popular.

Second, through this drama, the friendship between Lee Joon-ki and IU has continued to this day. Many media are speculating on the possibility of the two having a romance through drama.

During the filming of "Bu Bu Jing Xin: Li", many people were speculating whether they were together. Now that the show has been aired for many years, these news have not stopped. Even the CP fans about the two of them did not stop, and this time Lee Jun Ki showed up to watch IU's concert, which made those CP fans even more excited. After all, this is not a job at all, but a private friendship between the two. So It seems that the two of them have a lot of interactions in private, otherwise Lee Joon-ki wouldn't have taken the time to cheer for IU. ?

Finally:

In fact, I quite hope that they can be together. The Chinese version of "Bu Bu Jing Xin" brought Wu Qilong and Liu Shishi together. If "Bu Bu Jing Xin" "Jingxin: Li" also brought them together, it was really dreamy.
