What kind of personality is this? Does the MC live in an abandoned house for five years, find a portrait of the previous owners, and somehow feel indebted to them? That didn't even make sense, how does this guy live in society? What would happen if someone treated him politely, like he walks down the street knowing that there was someone who made an effort to build it? You took a Chinese MC's personality of repaying kindness and multiplied it by 100, with that precedent the MC should sacrifice his life for any small act of kindness. (Google translate)
I know the MC has to participate in the war, but that's it, it doesn't need some altruistic justification for it. He's in a simulation, him going to war should be a selfish desire to improve his strength and not die in the real world. Saving someone would make a lot of sense if they were a big fan of the character and didn't want him to die. And not this crazy "risk your life (simulation life) saving the son of the dead couple I never met but I lived in their house for five years and somehow I feel that even after they are dead they are happy from a complete unknown lives in their house".
