SEE ALSO: Upcoming drama 'Way Back Love' gains much attention ahead of premiere

Changmin and Moon Ga Young are seen leaning in for a kiss in the art room of their high school and Changmin's tears also brought out the sweet and delicate first love story.

The staff commented, "The kiss scene in the art room was filmed in two days. On the first day, they focused on their eye contact as they acted out the feelings of love for each other and on the second day, they focused on filming how their ardent feelings changed after the kiss. It is a scene which expresses the two's feelings most clearly, and the staff held their breath as they filmed it as well."

'Mimi' portrays the story of a popular webtoon writer Minwoo, who is on the search to find the first love he lost when he was younger. Changmin will portray both the younger version of Minwoo who falls in love at the tender age of 18 and the older version who lost her.

'Mimi' will premiere on the 21st at 11 PM KST!
