What happened to your PROMISE??? (Arcana Famiglia)

Feliza is Mondo and Sumire's pride. Until one Birthday, everything changed. One birthday, she lost everything. One birthday, she lost him, She lost Pace. One birthday, Felicita was born. What happened to his promise? No one knows. What will happen if a once very sweet girl, changed into a cold, arrogant, sadistic monster in just one snap? Who's the one to blame? Is it him? Her family? Or her new baby sister, Felicita? Will she ever have her happy ending with Pace? Or is it with someone else? THAT IS.. If it's a HAPPY ENDING

DISCLAIMER: I do not own any of the characters of Arcana Famiglia. I only own Feliza and Ivan. Thank you :)
