Kim Tae-heon released his second single album ‘If We Never Broke Up’.

This song is a song that brings back memories and regrets from long ago, and contains the realization that the ordinary conversation and day of the past was actually the greatest happiness.

This single features Kim Tae-heon's rap verse and female vocalist Su-a's hook, and TheGrand (Lee Seung-jae) and KWANWOO participated in writing and composing the lyrics.
