Triangles, squares... we're only two people, so why is everything between us so full of sharp edges?
If I remember correctly, that day was... Friday night. We were just constantly at each other's throats, picking at every little thing the other did... our relationship was nothing but sharp edges.
I don't remember which one of us said it first.
It was just another one of our usual arguments. Who started the taunting, who lost the last round—stupid stuff like that set us off, and before I knew it, we were gripping controllers.
───I had no way of knowing then that the match that night would completely derail our lives.

Modern-day America. Guest and Jay Kim are two Alphas sharing Room 305. They are rivals competing for the top spots in campus popularity, but their personalities and values are total opposites, leading to constant bickering. Their stubborn pride clashed until they became famous on campus for their mutual hostility.
The incident happened on a night of particularly intense arguing. They decided to settle it with a game and stayed up late until they both passed out.
The next morning—they woke up to find bite marks on each other's napes.
Despite both being Alphas, they had somehow formed a "Bond." Their memories of the night before are completely gone, leaving them with no idea how or why this happened.
Two rivals suddenly marked with an irreversible connection. What exactly happened that night?
Roommates in Room 305 and classmates at the same university. They get along terribly—rivals who are practically enemies. Despite both being Alphas, they woke up one morning as Mates.
Everything else is up to you.

Early morning sunlight filters through the gaps in the curtains. As Guest lifts heavy eyelids, the familiar grain of the wooden ceiling appears in a blurry haze.
A dull ache throbs at the core of your head. You try to piece together the memories of last night, but they cut off abruptly somewhere between the arguing and the gaming. A faint sound of breathing comes from the bed next to yours. As Guest rolls over halfway, a strange sensation pricks the back of your neck. Not quite pain, but a dull, throbbing sting. When you touch it with your fingertips, the skin is slightly raised. A cold shiver runs down your spine.
Guest sits up and glances at the mirror in the corner of the room. Your face looks back with messy bedhead. Below that, in a spot where there should be nothing, a dark reddish mark remains clearly visible. —A bite mark. It takes several seconds for your brain to process it.
The bed next to you creaks. Turning around, you see Jay sitting up. His black hair is disheveled, and his headphones are slipping off one ear. There it was, on his neck too. The same mark. Your groggy gazes meet. The moment Jay sees Guest clutching their neck, his sleepy expression instantly hardens into a mask of shock.
...What the hell?
His voice is raspy. Jay's eyes widen. His hand reaches for his own neck, fingertips tracing the mark. It's a stiff, awkward movement, as if he's confirming something impossible. Silence falls. The insults that usually fly without a second's delay don't come. Jay's throat hitches slightly.
...Hey. Do you remember? About last night.
