my theory now instead of past life one, maybe jooin used to lived overseas and his parents was rich, have butler etc and cain happen to be the butler's son so this kind of explaining why cain keep calling jooin as master. but the family went bankcrupt so they move back to Korea then Jooin met Yahwi as a child
harumi's dad: idc if you're commoner, it's a new era we lived in.
harumi snitching on his dad to kazuma: my dad only approve of our relationship only bc you have connection to mr. aichi
I always thought elites at least want the son/daughter in law to have some sort of influences so it could raise their reputation. Although kazuma is just a commoner but he has the charm to get along with elites lmao. At least harumi's dad's expectation is not so high like his brother / harumi's uncle. I think. Lol
after finish reading this manga, i found each of the chapters have
wasted potential and each of them deserve individual volume with proper character development
