PSTD is one thing.
Ungrateful and selfish is another thing.
I don't understand the need for MC to be nice to her. Unless he wants to conquer another waifu.
Somehow I hate MC for trying to be nice to her, too. It somehow seems like "hypocrite" to me. (This may be the reason she hates her)
Or Maybe the Author tried to make him a Saint.
It seems like her PSTD makes her lose truth in humanity. So, you'd better not trying to be nice to her.
Just outright telling her that "I did all that just because I want to save my daughter, whatever happens to you is just a by-product, I don't even know you and I don't care how you take it"
The more you chase, the more she pulls back.
But when you act like you don't care, if she cares, she might open up to you.
