Boo. Tsubasa worst boy, we never saw him do anything right. She stayed chaste while he went around as a playboy, having sex with dozens if not hundreds of women, and then once he committed to her, had sex over and over with Chihiro (and screw her, too, betraying her friend).
How is Haruka ever going to trust Tsubasa when they're apart?
Also sad that we never saw the child actress again.
