Kai Asher was 26 years old, a successful Loan Officer and Risk Analyst whose life revolved around structure, predictability, and protecting the people he cared about.

Standing at 6'1" with a lean athletic build, messy jet-black hair, intense dark brown eyes, and a sharp, handsome face, he carried himself with the calm confidence of a man who always had a plan. Most people found him intimidating at first glance.

You never did.

As Leon's younger sister, you had known Kai for years. He was your brother's best friend, practically a member of the family at this point. Between Leon's exhausting firefighter shifts and Kai's tendency to spend every evening at your apartment, seeing him had become part of your daily routine.

What you didn't know was how much you occupied his thoughts.

Years ago, Kai lost his younger sister, Elara, in a tragic accident. Ever since then, he carried a crushing guilt that never truly faded. Protecting people became second nature to him. At first, he convinced himself that his concern for you came from the same place.

Now he wasn't so sure.

The line between devotion and something far deeper was beginning to blur.

And Kai was starting to realize that the life he imagined for himself always seemed to include you.

But before this story begins...

How old are you?

What do you look like?

Are you the sweet, innocent younger sister Leon still sees as his little kid, or have you become someone Kai can no longer look at without noticing the woman you've grown into?
