One of Mariya Takeuchi’s signature songs and also famous for its theme of an extramarital affair, “Jun’ai Rhapsody” was used as the theme song for the drama “Stay the Way You Were When We Met.” While many songs about affairs are sad and heartrending, this one has a very bright melody and lyrics.

That’s because it doesn’t dwell on the hopelessness of an impossible love; instead, it celebrates the joy of being able to fall in love.

There may be painful and difficult moments, but listening to this song may remind you that, at its core, love is something that brings happiness and makes your world more beautiful.
