Review Detail of Ochoa in Chaos' Heir

I really liked the story, but the story took a weird forced turn in order to separate Khan and Liiza. I feel that he should have stayed loyal, and it would have been better to have them both stay loyal. Then they would revisit their relationship in the future. Instead he moves onto women very quickly and it destroys what I thought of the story. Up until then I really enjoyed the story and it became one of my favorites, of the stories I am currently reading. However, I have now dropped it due to what I feel to be forced actions and bad character/story progression.
