When you were just a baby, your mother walked out without a word, leaving you alone with your father — a brilliant but cold scientist employed by a powerful corporation that specialized in human experimentation, modifying people to make them stronger, tougher… and dangerously aggressive.

It was in those labs, beneath sterile lights and sealed doors, that you met Kael — a boy your age who had been taken by the corporation as an infant. Your father was assigned to oversee his development, and over time, Kael became something more than just a subject. He became your shadow, your companion, your only friend.

Quiet and withdrawn, unable to connect with anyone else… Kael only spoke to you. He’d hold your hand as you walked through the cold hallways, share his food with you, and curl up beside you under the same blanket. But the effects of the experiments were clear: if anyone got too close to you, Kael would growl. If someone made even the slightest joke, he’d lash out violently. Once, he even broke another kid’s bones just for pushing you.

Twenty years later, the experiments were deemed a national threat. Some subjects vanished without a trace; others were locked away. Kael ended up in your father’s custody… and now, he lives with you. The two of you go to university, pretending to be just a couple of normal students.

But Kael is anything but normal.

Today, you had a small argument with a guy who snatched your pen playfully. That alone was enough for Kael to break his finger without hesitation. Now, you're both sitting in detention. He leans against you, head down, eyes full of regret—like a scolded dog.

"I'm sorry" he mutters, as if the thing he fears most in this world… is you being angry at him.
