OlaT Entertainment released the teaser for Park Jung-min's digital single "Love So Sweet" on its official YouTube channel at midnight on the 11th. The video features lovely and cute charms like the cozy and comfortable acoustic song "Love So Sweet" with Park Jung-min and Ella of girl group PIXY.

In the video, Park Jung-min puts out a lipstick he chose for Ella, and Ella takes it with joy. Park Jung-min's soft, sweet mid-low voice and Ella's refreshing and pure voice, which flows behind the two's "Perfect Match," (Translator’s Note: 찰떡궁합 technically means a perfect match in Korean, so this is a play on words, though the song’s English name is different) create a lovely, sweet harmony.
