Theres not much they can do about it even if they do find out, since Kazura is the only one that can provide said food and any they are scared shitless of doing anything that would even slightly annoy him with the legends of what happened in the past.
@Huichelaar
Yeah in the long run its better for Isaac to know that Lieze was just stringing him along, i dont doubt he actually had feelings for her, but maybe now he can get over it and move forward.
Lieze on the other hand is in a for a rough awakening when she gets told off because Kazura just isnt interested in her.

Its an Isekai, most authors are ignorant of the actual developments made in the world history that dont concern Japan, but in the series favor, their technological advancements seem to be early bronze age, which fits the bill for Ancient Greece Period. I mean they didnt have water wheels, that shit came about in 4000 AD
@Harouki
His kindness and Valleta really are the things that keep him coming back, im sure in the future he is going to be pushed to decide.
@AbuHajaar
Lieze is going to get hers just like her step-mom did.
