The Ordinary Guy I'm Dating Is a Controlling, Overbearing Creep

At a club event, I met a tall, handsome man with long black hair. On the street, I handed him a charity gift. He watched me for a long time, then calmly walked away.

The next day, I spotted the same handsome guy at a crime scene. In a panic, I grabbed him and ran. "I heard they haven't caught the killer yet. We need to get out of here!"

One night not long after, I felt the temperature drop. I rolled over and pulled up my blanket. Sleepily, I opened my eyes and stared into a pair of pitch-black eyes. I jolted awake.

The man leaned over me like a ghost, his long black hair perfectly still. The nail in his hand was pressed against my skull.

"I can't attack you. Why... Is this your Nen ability, too?" He tilted his head. "I understand. The fight is over. If you release the Nen ability you've placed on me, I'll call off this assassination."

...Nen ability? Assassination? What the hell?!

My name is Elai Sierte, and I'm just an ordinary college student.

Since there are no ghosts in this world, I figure I must have run into someone with a mental illness.

The day before a mission, Illumi encountered a woman on the street. The moment he saw her, he felt something extraordinarily strange. He watched her for a long time and left only after confirming she was just an ordinary person.

The next day, before leaving after completing his mission, he unexpectedly ran into the woman again. She really did seem to think he was just some ordinary passerby. After confirming that she hadn't caught him at the murder scene, he finally gave up on killing her to silence her.

Then the strange things began.

For several days in a row, this person kept appearing in his dreams. The episodes grew increasingly intense, even affecting his work.

He had misjudged her. She was a Nen user.

After returning to the area where the mission had taken place and watching her for several days, he made sure she had no companions nearby. Then, after nightfall, Illumi decided to act.

While she slept, he drove a Nen needle into her brain... but it failed. Worse, she had already woken up.

Her ability and intentions were unknown. Attacking now was too risky, so Illumi decided to change his approach and call a temporary truce. "If you release the Nen ability you've placed on me, I'll call off this assassination."

He would find out what she was really like, remove the Nen ability binding him, and then kill her for good.
