While apologizing for past mistakes, the lyrics quietly sing of unwavering love for one’s destined partner, using the fragile motif of a candy to express both the sweetness and the ache of romance.
The single topped the Oricon weekly chart, sold a cumulative 388,000 copies, and ranked 13th on the year-end chart.
It’s a classic that presents a mature, romantic world, highlighted by the duo’s perfectly blended harmonies.

The lyrics and vocal delivery—firing off grievances and assertions with full force—make it a particularly distinctive track.

The interlude also features a saxophone solo, which is super cool.
SHALL WE LOVE ?gomattou
This is the only single from a limited-time unit consisting of Aya Matsuura, Miki Fujimoto, and Maki Goto—three artists who were showcasing their talents as solo singers within Hello! Project at the time.
It’s a cool, weighty dance number that leans more toward singer sensibilities than typical idol vibes.
