In "A Valid Love," Lee Soo Hyuk kissed Lee Shi Young out of the blue.

On the 4th episode of tvN Monday/Tuesday drama "A Valid Love" (script Kim Do Woo, director Han Ji Seung) broadcast on December 9th, Kim Joon (played by Lee Soo Hyuk) surprised Kim Il Li (played by Lee Shi Young) by kissing her.

On this day, Kim Il Li heard from Kim Joon that he couldn't recite his multiplication table. To help him, she went to his store.

Kim Il Li showed Kim Joon the multiplication table song and advised him to follow along. Then, Kim Joon refused saying, "I'm not an elementary school student you know."

As Kim Il Li continued to tell him how to memorize the times table, he said to her, "How is this anywhere relevant to you?" and refused.

Hearing this, Kim Il Li said, "If you talk about embarrassing situations, I'm even more embarrassed" as she talked about having breathing complications in the past in front of him.

Hearing her intentions, Kim Joon got upset again and shouted at her, "Did you really come here for the times table?"

Kim Il Li answered, "You know. I'm sorry to act like a know-It-all but this isn't something to get angry over." At that moment, Kim Joon surprised her with a kiss.
