Snow WhiteFlower

A song by Flower inspired by the world of the fairy tale Snow White.
Like Snow White waiting for the prince’s kiss, it’s a poignant love song about a woman waiting for the person she loves to come to her.
Many listeners may relate to falling in love even while knowing the man they like has someone else, just like the woman in this song.
Love isn’t governed by logic, so once you fall, it’s hard to stop.
Although the song ends on a bittersweet note, it still conveys the strength of a woman who single-mindedly stays true to her love.
C.O.S.M.O.S. ~Cosmos (Autumn Cherry Blossoms)~Sandaime Jē Sōru Burazāzu fromu Eguzairu Toraibu

A song that’s also popular as an affair-themed track: “C.O.S.M.O.S.
~Akizakura~” by Sandaime J Soul Brothers from EXILE TRIBE.
It’s a great pick for anyone looking for a bittersweet love ballad from a male perspective.
From the very first lines, the lyrics hint at a fate where the two can never be together.
It’s truly a song about love that came “too late.” Even when your head knows you shouldn’t let your feelings grow, the more you sense it’s a love that can’t come true, the less you can stop your heart.
Meeting your destined person after you’re married is so cruel…
codependencyDomura Riu

A work by Riu Domura that candidly portrays the fragility and pain of a mutually dependent relationship.
This song depicts the heartrending figure of someone who, even while understanding it isn’t true love, cannot bear the loneliness and continues a false relationship.
Even knowing they’re just convenient, they can’t break away from the joy of being needed.
You can’t help but empathize with the protagonist’s conflicted feelings.
Released in May 2019 on the EP “Escape,” this piece suggests that, even knowing you’ll end up alone, being unable to stop may be the inescapable reality of a forbidden love.
Play ball!YU-KI

To mark the milestone of her 10th anniversary as a solo artist, YUKI delivered a song that evokes the beginning of a forbidden love.
Contrary to its bright, cheerleader-like sound, the worldview seems to portray a woman’s strong will as she plunges into the game of love without thinking of the consequences—“even if it’s a strikeout.” Her desperate plea for divine help conveys the pain of being unable to stop her feelings, even while knowing the relationship is forbidden.
This monumental single was released in May 2012.
Even though you know it’s wrong, this is a song that confronts your heart with a certain resolve to stake everything on this love.
WHYKato Miria

This song, Miliyah Kato’s “WHY,” vividly sings about a woman’s unstable state of mind, where anxiety and expectation rise and fall in turn.
Many women, while getting their hopes up at suggestive behavior, secretly worry, “Maybe I’m not the most important one to him…” In those moments, they end up blaming the man, only to be hurt again by his response.
It’s not that they truly want to accuse him—they just want to be loved, just like in this song.
LOVE AFFAIR ~Secret DateSazan Ōrusutāzu

“LOVE AFFAIR ~Secret Date~” is the Southern All Stars’ 41st single, released in 1998.
“Love affair” means things like an “affair” or “tryst,” and, true to its title, this song is about an extramarital relationship.
It’s a song where you can feel the complex emotions and a man’s weakness: I love you, but I can’t throw everything away.
