You doublepost and "QFT" two completely contradicting opinions. The first saying Koto should end up as Makoto's girlfriend, and the second saying you wish she'd never met him.

I definitely think Koto deserves a decent man, but I fear she'll end up fighting for a guy that won't be worth a minute of her time. I think it'll be a painful, if not traumatizing experience for her.
