The song is also featured as a track on their Japanese debut studio album, 1.
The single was written by Wheesung and composed by Lim Sang Hyuk, Jeon Da Woon, and Lee Sang Ho.
In June 2012, B1A4 began promoting another song off their debut mini album, "Only Learned the Bad Things." "Only Learned the Bad Things" was written by Wheesung. The music video for "Only Learned the Bad Things" was released during the show "Match Up" that both B1A4 and Block B are participating in. 
The music video mainly features Baro who plays the role of an ignorant boyfriend. Throughout the video his selfish actions are portrayed through various acts in a store such as dismissing his girlfriend when she asks for his opinion on jewelry she intended to purchase, disappearing to fit on clothes without notifying her, and not answering her text messages. Small breaks are taken away from the storyline to feature all the members performing to the song in various room-based sets.
Once Baro reads her text message intending to dissolve their relationship he realizes his faults in respecting and loving her. He gathers all the members to throw a surprise party for her and their relationship is strengthened again. The video concludes with the members rejoicing with the camera focusing on a sticky note attached to a Tropicana can.
