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…

This is Miliyah Kato’s “Ai no Kuni” (“Country of Love”).

It’s a sad song about a devoted woman who fell in love and shared a kiss even though she knew he belonged to someone else.

She believes that one day he will choose her, that he’s her destined partner, and she waits.

The things that would be natural for lovers can’t be hoped for in an affair.

Even so, the aching feeling of not being able to let go of this love comes through painfully clearly.

It’s a song that gently nudges those trying to move forward, even while carrying lingering feelings.

“Shizuku,” released in 2020 by the rock band Marcy.

Even knowing the other person is married, if they invite you, you can’t turn them down because you love them; if they call, you end up going to see them.

It’s a song that sings of that painful feeling.

When you’re only contacted at their convenience, you can’t help but wonder if you’re just being used… but when someone you love is kind to you, it makes you happy and you can’t push them away.

This track pierces you with its vivid scenes and raw emotions.

I hope both men and women—everyone caught in a painful love—will give it a listen.
