Next Chitose will will ask Ayaka to cut her hair in a stunning show of camaraderie.
Then a stunned Ayaka will further trim her hair in order to match Chitose's resolve.
But then Chitose feels that in order to properly honour Touka's memory she must trim her hair even more. Because every lock of hair that falls symbolizes their love that could never be.
And this will continue until they're both bald.
Story continues in the hit sequel: Bald but in love
