Since I love cherry blossoms, I also love love songs from cherry blossom season, and this one has the straightforward, unadorned lyrics of FUNKY MONKEY BΛBY’S that feel so perfectly youthful.

Back then, I used the Inokashira Line mentioned in the lyrics, so I listened while relating it to my own life.

At a friend’s wedding, I was struck by how the groom passionately sang it to the bride.

This is one of Sukima Switch’s most beloved signature songs—an ultra-popular track that almost always appears in features about tearjerkers and ballads.

The accompaniment, which incorporates not only piano but also strings, has a beautiful impression, and vocalist Takuya Ohashi’s gentle, heartfelt singing is irresistible.

Listening only to the chorus lyrics might make you think it’s a breakup song, since it depicts a parting scene, but if you look at the lyrics as a whole, you’ll see it’s a song about a couple who are about to enter a long-distance relationship.

Even if they’re far apart, it expresses their determination that their hearts will remain connected.

That’s something only two people who truly care for each other can say, isn’t it? Their strong bond feels like it shares a bit of their happiness with us.
