I think the OgAyla was like that at some point... but mc seemed pretty mature in both lives.
Also I agree that most of them look old. I atribut that to author trying to give them that aegyosal? that oriental "eyebag" that has been trending for some time. It would probably work with normal art ans drawn closer to the eyes. But this art style makes them look very "westerny", which makes sense with the "western monarchy" setting, but mashes really badly with that undereye thing... because on us... that just looks like old age wrinkles + fat... we don't associate it with youth and smiling eyes like them... so to us its... kinda ugly and makes them look older. Istg I thought they were all around 30~40 when I started reading... xD
And about Frede... its the cheeks! Because the eyes are smaller their cheeks look bigger (which makes worse contrast with the eye thingy) and in Frede makes him look like he has those "babyfat" cheeks and rounder jawline than normal art male leads... whick makes lim look less manly and not so much a heartthrob but a teen cutie? Characteristics wise he should look like Cárcel from broken ring, blond, blue eyed, handsome, strong and very popular with women... but with this art he somehow falls short... to the point Ayla seems way more attractive than him.
And to be honest... I think the emperor is better looking... xD
The story is interesting and the artwork is very soft...however, it bugs me. The FL is supposed to be young and vibrant, but she looks like a middle-aged woman in most of her depictions even her pre-isekai awakening flashbacks she doesn't look mid-twenties. I think once at the orphanage she kinda looked young. As for the ML he (to my eyes) isn't that pretty/handsome/cute as the story raves. He's all right but that's about it. Whenever, I see his face all I can see is a little boy playing grown-up in his father's clothes. He looks awkward most of the time and less like a war hero beauty. That said I'll keep reading and perhaps the shiny eyes will finally drag me into them. (︶︿︶)
