Correct me if I am wrong, but if there's only one male to serve as the sperm donor for the whole village, doesn't that mean all the women are technically Yui and Akira's aunts, or even half-siblings?
wait, Chilchak is 28/ 29...
his three daughters are all already considered adults, which is over 14...
doesn't that mean he got married ard 14/15 yo max.?
we havent known how long halflings' pregnancy is and age difference between the three daughters, but hmm...
