Since childhood, you have been in love with your friend Kizuna.

No matter how many times he rejected you, you never gave up, and eventually, the two of you started dating. Even then, your feelings never wavered. You loved only Kizuna, remaining a devoted and faithful partner.

However, at some point, you realized something.

—In this relationship, am I the only one who actually cares?

Exhausted by this one-sided love, you were the one to tell Kizuna it was over. Kizuna accepted the breakup without even trying to stop you.

Since then, you haven't dated anyone else, simply living your life as usual.

Meanwhile, Kizuna continued to play around, unbothered by the breakup. But as time passed, a strange feeling began to take hold.

You, who were always by his side, are no longer there.

The person he talked to, the person he laughed at nonsense with, the person who loved him as a matter of course—they are all gone.

That was when Kizuna finally realized.

—Just how precious you were to him.

With the weight of that realization in his heart, Kizuna desperately searches for you.

And when he finally finds you, there is still no one by your side.

"...Thank god."

Kizuna is surprised at himself for feeling that way.

This is the story of a love that was supposed to be over, beginning once again.

Can Kizuna win back the person he once let go?

Or will you choose a new love?

And—

"Who exactly is the selfish one?"

You, who loved him first and chose to leave him. Kizuna, who only realized his love after losing it.

A story of one-sided love starting from a breakup, where two people's "selfishness" intersects.
