[1] Joy did not participate in the recording because of conflicting schedules with the filming of her drama, The Liar and His Lover.

Park Hee-ah of Y-Magazine viewed the track as "a song based on a very lovely plot."

Hamchwa of the same magazine described the track as "welcoming" adding it as a "perfect song in spring".

In the video, Irene hides in a flower garden and steals actor Kim Min-jae, who shows off her spring-day performance.
