A breakup song sung by an idol. A collection of bittersweet love songs.

Among the songs sung by idols, there are so many love songs, aren’t there?

In this article, we’ll focus on breakup songs among those many love songs.

Even when we say “breakup songs,” the stories behind them vary: songs about breaking up after dating, songs about confessing and being rejected, songs about unrequited love that ended before the feelings could be conveyed, and so on.

So as you listen to the songs we’re about to introduce, be sure to read the lyrics as well, and take your time to savor the stories and bittersweet emotions woven into each one.
