On March 22nd, Ga-In performed her hit duet track, "We Fell In Love" with B2ST's Doojoon on the 85th episode of MBC's "All My Love"! The duet was inspired by a reminder of a promise the two had made in which they said they'd sing a congratulatory song for the wedding of a high school friend. Geumji (Ga-In) and Doojoon are called upon to complete this promise, and so they're forced to overcome their awkwardness with one another in order to fulfill it. Geumji had asked Doojoon to back off from her life in an earlier episode, but the two managed to come together for this event. Soon Duk (After School's Lizzy), Doojoon's new girlfriend, tags along to their rehearsals, and Geumji can't help but consider her troublesome.
