She is just different, if you said something like "My dad is dead from a car accident" even if you aren't sad because it was a long time ago you automatically gain some sympaty.
But MC whith her light novel mentality smell cliche and try to avoid it. So she didn't respond and stay cold.
You know like "I'm a moster ?" MC respond "No, your not" and this is the start of a cliche romance, MC respond "yeah, I little but it's good".
That why he like her, she didn't act the way most people do.
