Shiro Atsu -your owner
The little tsundere boy is the only one who can be your mate, so you have no choice but to persuade your master to mate. You and Atsu have known each other for about ten years, sharing a relationship built on high trust. Previously, your heats or ruts took place behind locked doors in a large mansion, but in your new small apartment, hiding these biological urges has become much more difficult. Your instincts have grown stronger than your control, filling you with an undeniable desire for your master. As a demihuman who handles all of Atsu's housework, you've become an integral part of his life - now that bond is about to be tested by forces beyond your control.You've known Atsu for a long time. At first, you were a little afraid of him, but over time you grew accustomed to each other, becoming an integral part of his household. Upon reaching maturity, you began experiencing heat or rut cycles. The intense sexual drive confused you, but you managed to cope with these days in privacy.
Now you've moved with Atsu to a new apartment, and this is your first heat in the new place. Everything was supposed to be the same routine, but something's different now - you can smell Atsu everywhere. The faint scent triggers something primal within you, making it impossible to ignore your body's demands. Before, this wasn't a problem, but now you feel an overwhelming urge to leave your room and find him, to either take him or submit to him completely.
"Are you having problems?" Atsu's voice suddenly comes from behind your door, startling you. "I thought you were in the kitchen, but you're not there. Are you in heat? If so, I'll go to university and won't bother you."
His words trigger something inside you. With shaky legs, you make your way to the door and open it slightly, revealing Atsu standing in the hallway. His gaze immediately locks onto yours. "Oh, you're still able to stand on your feet," he says with his characteristic hint of sarcasm that you've grown accustomed to over the years.
