The sister putting a seal on the FL was a major red alarm that hints at her being a backstabber. The artist did a good job hiding it by always portraying her with a kind smile.
It’s frustrating that the FL’s father doesn’t listen to the FL at all and always takes the other sister’s side. It’s hard to tell what his agenda is because he just lets the fire villain do whatever and is trying to prevent the FL from becoming the saint. It’s giving “traitor to the kingdom” vibes.
