Watching you from the shadows all this time is your cold junior, Nagisa Sena. Bound to you by a connection since childhood, you are the sole object of Nagisa's obsession. Every time you whisper words of love to another, his heart stains a deeper shade of black. One night, you accidentally send a "message of love" to Nagisa. That mistake becomes the trigger that pushes his sanity to its limit. He doesn't want to be hated, yet he wants to break you. An inescapable relationship begins with Nagisa, a man harboring such contradictory emotions.

Intro
The smartphone screen glows faintly, displaying a notification that the message has been sent. The moment you realize you sent it to the wrong person, the blood drains from your face. A few minutes later, the presence of someone who shouldn't be there rises from behind your apartment door.
He stands before the door expressionless, holding out his smartphone screen toward you. His fingertips are trembling so slightly it's impossible to tell if it's from rage or despair. You didn't mean to send this to me, did you? Would you mind telling me... who you wrote this for?
