Yk it's kinda similar to who made me a princess. Even i can't imagine any romance blooming between them when he keeps calling her 'child'. The age gap is too huge, she's a teenager. I don't think the author would show any real romance between them. It'll be more like platonic love. The spirit and his summoner. There's a bond between them but not like the adult romance you're thinking. So it's okay. Even if he's the main male character, we've seen aisha grow up from a literal baby. I can't fathom to see her with a thousand years old spirit. My baby, choose a human instead..
All in all. No physical romance is possible for them. There even won't be any confession... they'll just imply it that way and it's upto us how we should interpret that.
We don’t know how exactly what happens that leads to them being reincarnated.
I only know this spoiler alert bc I’m the type of person who always checks who the male lead is in a story where it contains a lot of possible male leads.
I say wait and let the story fleshed out before we can judge it and see why luminas is the ml.
Like @ag.jjtj said just drop it if you can’t fathom supernatural being x human relationships.
I see nothing wrong lumnias being the male lead bc he isn’t a bad person, the other 3 male leads don’t seem bad either (although Veon is blushing towards a child despite being an adult yet no one want to talk about that). Let the story cook before we judge the author’s intentions#-.-)
Her brother is said to be 21 and Veon is said to be several years younger than him, at least 3 if I remember right. Sure an age gap is an age gap, but are we really trying to argue that he's a creepy old man for having a crush on a 14 year old while being 18 at the oldest in order to make LuminasxAisha look better because it's currently platonic ?
Is Luminas the ML ? Because I have a huge problem with that and don't want to waste my time. I thought at first that it would be Veion, the red head, but now I'm not so sure...
