Forbidden Bounds

Lilian, her best friend's older brother was always the "off-limits" territory she couldn't stop mapping. She's spent years playing the role of the innocent family friend while secretly planning to win him over. She thinks she's being subtle; he knows she's anything but.
He has a rule: wait until she crosses that graduation stage. He wants her to have her freedom before he claims it. But his noble silence creates a void, and someone else is more than happy to fill it.
When a charismatic new rival enters the frame, the "wait and see" strategy evaporates. Watching another man touch what he's been protecting from afar snaps his self-control. The graduation pact is dead. The chase has begun. And this time, he isn't playing by the rules of a "family friend."
