He's basically a kid stuck between his crush and society.
The waitress girl WAS a noble, but their country fell to the demons and she and her sister were told to escape.
However other nobles slander them as coward for running away, leaving her with rather deep trauma about it.
He was something of a childhood friend to her and unlike others he genuinely was worried about her safety (hence Eris's intuition pointing to him being a 'good guy')
When he found her, he was just glad she's alive.
However before he could say anything the others noticed who she is and started slandering her first then Makoto interrupt them before he could do anything.
Even in his dying moment, his thought was simply "I just wanted to talk to her"
