The Repairman I Picked Up Is a Retired Soldier King

She is a queen of the business world, having built a commercial empire with her own hands. She believes there is no one she can truly rely on. He is a special forces soldier forced to retire due to injury, carrying the trauma of losing his entire team and locking his soul inside a prison of memories. By chance, he takes her home when he finds her drunk. He means to go their separate ways, but then witnesses her caught in a deadly web spun by her family, the business world, and foreign forces. Forced to act, he goes from protecting her in secret to fighting by her side. She teaches him to let go of the past, and he helps her understand that even a queen can have a knight and castle of her own.
