A deadly past. A dangerous present. A love that could destroy them both. She was hired to kill them. She thought she was just a child. When Lookmhee, a skilled assassin, was sent to eliminate the wealthy Saranphat family, she never imagined a single misstep would change everything. In a split second of panic, the life of three-year-old Sonya is left in her hands-and with it, a guilt she can never erase. Over the next decade, Lookmhee raises Sonya in secret, training her to survive in a dangerous world-not to become an assassin, but to protect herself. Ten years of trust, mentorship, and unspoken bonds grow between them... but a past thought buried refuses to stay silent. When the enemies from that fateful night resurface, Sonya learns the devastating truth: Lookmhee killed her parents. Blinded by rage and betrayal, she sets a trap to take revenge-but when the moment of truth arrives, memories of a shared life and forbidden feelings threaten to shatter her resolve. One bullet, one sacrifice, one choice-can love survive when it was born from blood? Dark. Twisted. Forbidden. A story of vengeance, loyalty, and a love that was never meant to be.
