the story will unfold on later chapters and its worth the read
but if you really want to know, im happy to answer ^^
1. the heart of the red prince is from Gaia, the MC's mom
2. the MC's dad isnt a traitor.
if you want to know more, here's some more spoilers
He and Gaia saw a frail injured man and helped him recover. Little did they know that he was an Exiled doctor i think. When he recovered, he came back to them and kidnap Gaia and almost killed the MC's father. So the doctor experimented on Gaia because he wanted to get some mana stone i think which can make chimeras. They also stole her heart to keep the Red Heared Prince alive. Without her heart, Gaia used her last amount of power and escaped. She found her husband and gave birth to her child, the MC. But she sadly passed away after that. The father took care of the MC for 5 years. But the father became sick and getting frail. So he asked a favor from his brother to take care of her but sadly he only took the money and flew away, leaving the MC abandoned
