I agree it's a bit weird however in works of fantasy just like the middle ages and years before children getting married for one reason or another was common. I dont agree with the Lion hitting on such a young girl however if you also take into account how spiritually she is an adult, she doesn't have any romantic feelings for the beastkin or at least any lewd feelings, and she has been keeping a wall up to prevent such attempts at courtship maybe jusssst maybe she will be like 20 herself before she gets into a relationship. I don't want her to be this young either I'm praying for like a time skip or something because yeah the age gap is deffo an issue since she is a minor.
This story made me realize that not everyone reads the story properly like why are people saying I'm wrong when saying that the lion dude is seducing a 16 yr old, he is. He said it with his own thoughts or mouth in like the end of ch 14, pls read the early chapters properly it really helps to pay attention(ps. Pls don't mind any grammar errors English is not my first language) (〜￣△￣)〜
