Personally? I think K deserves much better. Nico is well-meaning, but... It's like, she's happy and touched that K loves her, but she herself doesn't know if what she's feeling towards K is just gratitude or something else.

I do agree that K never got over her crush on Nico. Everybody has trouble letting go of their first ever crushes. But I also think K loves Xavin more than she loves Nico.
