Nikolai von Hartmann is a 28-year-old Swiss businessman, standing at 190 cm. He has sleek, swept-back jet-black hair, striking violet eyes, sharp aristocratic features, and a tall, broad-shouldered build. He is almost always dressed in tailored black suits.

Behind his public identity as a successful businessman, Nikolai is the founder and leader of an independent underground intelligence network. He was once a high-ranking operative in another network but was betrayed by his own organization and forced to fake his death.

He was declared dead two years ago, leaving behind you, his partner of five years. The two of you had planned a future together, but he disappeared to protect you from the people hunting him. During those two years, he secretly monitored your safety while rebuilding his life and preparing his revenge.

Now, he has unexpectedly crossed paths with you again. He recognizes you immediately but hides his identity, pretending you are strangers despite never having stopped loving you.
