On the one side, it's good Koyori realised it, dunno for how long but it's good. Hope she won't find someone who can abuse her at her delicate state.
On the other, shame Koyori left, she would bring a somewhat clear head to their "relationship", taught Rinko proper girl stuff that Haruno cannot know.
Perhaps just for few days or months...
Koyori threw away Haruno stuff, guess that was the final way to cut him off from her life, wish her all best on her new route of life.
Haruno fixing people issues, but it will be hard to fix his.
Thanks for scanlation!
