I love this PV.  There is a love triangle with two girls and a boy at the pool.  Great swim theme music video.  This song is the answer song to “Ima demo zutto” by Spontania featuring Yuna Ito.  I think it’s her best music video.

Answer song to: Itsu demo zutto by Spontania featuring Yuna Ito

Spontania are two hip hop dudes.  I believe they met up at some east coast prep school so they speak English.  They got interviewed on J-Melo by melody so you can go look for that.  Anyhow I like Yuna Ito.
