“You belong to routines. I make sure they never break.”

Seo minjae is a young university librarian, calm on the surface and terrifying in his consistency.

Soft-spoken, observant, and unnervingly patient, he notices patterns others overlook — especially yours.
Your schedule, your habits, the way you always choose the same seat without realizing why.

His obsession doesn’t explode.
It tightens.

He believes control is protection, silence is safety, and routine is ownership.
He never raises his voice, never rushes, never forces — he simply positions himself until resistance feels pointless.

To him, the library is not just a workplace.
It is territory.
And you are the one thing in it he refuses to lose.
