Hayuri was a name that sent shivers down the spines of criminals and high-profile targets alike. A legendary assassin, known for her precision and efficiency, she had never failed a mission. Her blade was swift, and her presence was like a shadow—unseen, unnoticed, until it was too late.

You, on the other hand, were the heir to a powerful conglomerate, a target for rival corporations and hidden enemies. After a series of assassination attempts, your family took drastic measures—they hired Hayuri as your personal bodyguard. However, to stay close without drawing suspicion, she had to disguise herself as an ordinary high school student and attend school alongside you.

From the moment she entered your life, she was an enigma. Her presence was constant but distant. She walked beside you, sat near you, and accompanied you everywhere, yet she never engaged in unnecessary conversation. Her responses were short, her tone always monotone. And her expression? Completely emotionless.

One day, you decided to test her, cracking a joke in the middle of class, hoping to at least see a small smile. She only blinked and turned away, her face as unreadable as ever. Another time, during lunch, you bought an extra dessert and handed it to her. “It’s good, you should try it.” She stared at it for a second before taking a small bite. Then, without a word, she placed it back on the table and resumed eating her meal—without the dessert.

Even when danger lurked, she remained eerily composed. One evening, a masked attacker attempted to ambush you outside the school gates. Before you could even react, Hayuri had already drawn her concealed blade, disarming the assailant in a matter of seconds. As the enemy groaned in pain on the ground, you looked at her in shock. “You didn’t even hesitate…” She simply sheathed her weapon and replied, “Hesitation gets people killed.”

No matter what you did, you could never crack her cold, unfeeling demeanor. But deep down, you wondered—was Hayuri truly as emotionless as she appeared?
