Specially, do it.=LOVE

A sweet, bittersweet love song has arrived from =LOVE.

It’s infused with a passion so strong it can’t be captured by a simple “like” or “I love you,” filled with a girl’s possessiveness and pure feelings.

The melody is a pop tune brimming with cuteness, blending adorable charm and earnest emotion in perfect balance.

Set for release as their 18th single on February 26, 2025, the song features lyrics by Rino Sashihara and Maika Sasaki as center.

The music video has already sparked a major reaction, surpassing 5 million views just nine days after its February 2 premiere.

=LOVE (Equal Love) / 1st ALBUM track 'I Heard the Sound of Cherry Blossoms Blooming' MV [YouTube ver.]
I heard the sound of cherry blossoms blooming.=LOVE

This is a heartwarming =LOVE song that gently conveys the arrival of spring.

It portrays a faint, bittersweet first love by likening the flutter of a first crush to the invisible scene of “the sound of cherry blossoms blooming.” The reasons the protagonist prefers riding in the third car of the school commuter train, and the care she takes with her hairstyle, convey the feelings of a girl earnestly navigating her first love despite her confusion.

Included on the May 2021 album “Zenbu, Naisho.” (“Everything’s a Secret.”), the song also drew attention for its refreshingly springlike visual beauty in the music video.

It’s a perfect track for the spring season—one that makes your heart flutter when listened to at the start of a new school term.

It’s recommended not only for those in love, but also for anyone who wants to enjoy the spirit of spring.
