[All] A comeback on January 6th with a breakup song expressed as a cheerful dance song

Boynextdoor is making a comeback on January 6th

The title is "I LOVE YOU Only Today" and it is said to be a dance song that cheerfully depicts the realistic aftermath of a breakup.

They say it's a breakup song in the MZ style, and I was curious about what kind of song it was.

Most breakup songs are sad ballads, but Boy Next Door's breakup song is a cheerful dance song.

I want to hear it quickly
