Allegretto

The third new song "Allegretto" is considered to be a growth song link.
This song is a growth song that is said to be the follow-up to "Modokashii Watashi" and "MW2" released during the Modokashi Markets era.
It embodies the parts that could not be fully expressed during the Modokashi Markets era, but were able to be expressed as it evolved into INSRiA.
The lyrics were written by member Ayano Kizuki, who is writing the lyrics for the first time.
Sakura Amemiya is in charge of the lyrics part.
