She watches him pretend to care, then stops pretending back. One minute is all it takes to show what happens when someone finally gets tired of being useful instead of loved. The song doesn't ask you to feel sorry for either of them, it just watches her walk out, and that's enough.

Kimagure Mercy is an animated music video made to accompany Hachioji-P's best-of album, Eight -THE BEST OF 八王子P-. A woman reaches her limit with a shallow man who only pays attention to her when he wants something. After hearing one excuse after another and putting up with his lack of real interest in her, she decides she has had enough and leaves him.
