Honestly i have a theory that makes things so much worse.
What if the reason the mom broke with the dad was because the curse she was given gets transferred to the last person with her when she dies, which is probably MC since she died during childbirth. So she basically did it because she loved the dad so much that she would rather have MC die so that he wouldn't get cursed after she's gone.
It's a bit of a reach but what if the curse is something cheesy like it transfers to the person you love closest to you or smth and expected that the dragon clan and MC wouldnt love each other at all, effectively making it so that MC will die and the curse ends there.

i'm blaming the mom. sorry, i feel like she's selfish for leaving her child with the dragon clan when the father is literally alive??? yeah she's worried that she doesn't want him to see her die bUT DID YOU NOT THINK ABOUT THE FUTURE OF YOUR CHILD? idgaf that you were cursed and did it for a reason. dumb bitch lol sorry i'm just so mad bc the amount of trauma the mc went through??? can you imagine a little girl thinking that bread and reading books are small luxuries? i feel so sad for her.
oh the dad is stupid i know. i get that he locked up his emotions bc of what the mother but did you locked up your common sense as well? why tf did it take you so long to actually verify the mc as his daughter?
these adults are stupid!!!!! anyway i'm here for michael and michael only ٩(๑❛ᴗ❛๑)۶
