Limited edition "I wonder"

The song will be used as the theme song for the TBS Tuesday drama "Kururi: Who Fell in Love with Me?"
Member Taiki Kudo wrote the lyrics, while Sota Hanamura wrote both the lyrics and the music.
The two themes of "love" and "finding one's true self" are expressed through colors.
It's a song that goes from colorful to black and white, and then colors are layered back on top of each other.
