RADWIMPS is a rock band that has been active since 2001.

This is “Netsujou no Namida” (Tears of a Tropical Fish), a song released in 2014 by Flower, a female dance and vocal group that sadly disbanded in 2019.

It depicts a woman’s feelings as summer brings back memories of a past lover.

It seems to have been a painful romance; although she tells herself she won’t go back to those days, the way she likens herself to a fish in a tank shows she’s still trapped in the past.

Since it was her first love, it’s only natural she can’t forget.

A classic by Flower that you’ll want to listen to when summer comes.
