OnlyOneOf’s Underground Idol project was on track to maintain its once-a-month course until the group took a few weeks to promote their Japanese single. Because of this, Rie’s long-awaited solo became even more long-awaited, pushed back an extra month. Now, it’s finally time to land back in the guys’ BL universe. The rock-tinged Because continues where Junji’s Be Mine solo left off.

Because offers a lighter touch that compliments Rie’s vocal tone. He’s always been one of my favorite members of the group and one who seems pretty underrated amongst fans. This track doesn’t stretch his skills, but its constant embrace of melody sneaks up on you. If I were to give Because a description, I’d call it “softly anthemic.” Some songs beat you over the head with challenging textures, but there’s something to be said for music that plays like a gentle breeze pulling waves of sentiment your way.

The filtered guitar that opens the track has me like putty in its hands. I’ll always be a sucker for this sound. It’s wistful and nostalgic and laces its pathos with a sense of optimism. I’m not sure the songwriting always lives up to this potential, but I love when the melody gets a chance to soar. The build-up to the chorus is especially nice and the hook scores bonus points for its canny reference to “Call Me by Your Name.” A robust vocal arrangement could’ve taken advantage of layering and harmony to add even more heft, but that’s harder to accomplish with a solo performance. Even without the bells and whistles, Rie’s evocative tone goes a long way in selling the vibe.
