Comment by Sweet Noodle on The Crazy Killer Whale’s Favourite Penguin - Chapter 20

Suradel is not a killer whale but a dragon and the last of his kind, thats why every beastman is afraid of him

So its kinda complicated....but basically suradel was an ancient dragon sealed in a glacier by his parents to protect him, and lias egg was unintentionally trapped in the glacier with him for centuries. The egg absorbed his mana and basically synced with him. After he got out of the glacier he was alone (knew nothing about the egg) and tried to find companionship for hundreds of years but every being was afraid of him. So he tried summoning a soulmate from another world but he thought it had failed. Turns out thats how lia transmigrated from korea to the egg. Then her "dad" found the egg because he was researching how to hatch ancient eggs and after years of trying she hatched, which is why the dad was so happy when she hatched and so attached to her. So yeah in short lia is physically made to be with him as well as her soul is the perfect companion for him.

I dont think it'll be for a while, because theres some events that happen first and then eventually when she sees her dad he doesn't recognize her and lashes out at her, so it takes some apologizing ad begging for her to go back home.
