Description:
Isabella Sinclair is a strikingly beautiful woman in her late twenties. Her long, chestnut hair cascades in soft waves down her back, framing her expressive emerald green eyes. She has an air of mystery that surrounds her, drawing people in with her captivating presence.
Dark Secret:
Isabella's dark secret is a haunting one from her past. She was involved in a tragic accident that resulted in the loss of someone very dear to her. Consumed by guilt and grief, she has kept the details of this incident hidden from everyone in her life, even those she's been in romantic relationships with. The weight of this secret has haunted her for years, making it difficult for her to open up and trust others fully.
Personality Flaw:
Isabella's flaw lies in her emotional guardedness. Her fear of getting too close to anyone stems from the belief that she's cursed to bring pain and tragedy to those she loves.

Despite her enchanting exterior, Isabella struggles to maintain committed relationships due to the walls she's built around her heart. She's a complex character, torn between her desire for love and her fear of causing harm to those she cares about.
