SEE ALSO: CNBLUE's Jonghyun and Juniel release 'Love Falls' MV + 3 BTS videos

This version of the music video for the song focuses on the two's sunbae-hoobae relationship inside a classroom and left fans feeling giddy with the playful flirting and eye contact.

Regarding the filming, Jonghyun revealed it was hard to keep a straight face! He shared, "To be honest, I had a lot of NGs because I kept laughing while trying to act out the couple scenes with my close hoobae Juniel. It was also awkward to wear a school uniform even though I'm 24 years old. But I gained strength upon hearing that it suits me."

Juniel said she couldn't keep her laughter back either as she shared, "I'm very familiar with having Jonghyun sunbaenim around so I burst into laughter a lot. I made quite the effort to focus on getting into the feelings of the song."
