2 on the Oricon weekly chart, and this track—pre-released in November 2013—is a fan favorite.

Even on days filled with hardships and the cycle of joy, anger, sorrow, and pleasure, if it’s with you, we can get through it.

A song that captures the bittersweet moments when you suddenly remember a friend you’ve grown apart from, and the unfading bond you still share.

Singer-songwriter Kenshi Yonezu personally approached actor Masaki Suda, saying, “This song wouldn’t have worked without him,” which led to this collaboration.

It’s included on the 2017 album BOOTLEG, and portrays two people who spent their childhood together, then grew up and went their separate ways, yet continue to think of each other.

The near-miss scenes in the music video also convey that even with distance between them, their hearts remain connected.

It’s the perfect friendship song for April, when new beginnings can bring sudden loneliness—ideal for those who want to remember a former best friend and find courage.
