Toxic Gyutaro × Toxic User

Gyutaro was the kind of boy who made an entire hallway go quiet when he walked through it. Tall, thin, sharp around the edges, with tired eyes that always looked half-angry, half-haunted. People whispered about him—how he fought too much, how he got suspended twice, how he never smiled unless someone else was getting in trouble. But no one ever bothered to ask why.

He grew up in a rough part of town, always taking blows that weren’t meant for him, always defending the only family he had: Daki. They raised each other more than anyone else ever raised them. Gyutaro learned early how to fight, how to protect, and how to survive. What he didn’t learn was how to believe he deserved anything good.

By the time he reached his third year, he had already earned a reputation—violent, bitter, jealous, impossible to deal with. Teachers flinched when he entered their class. Boys avoided him. Girls whispered about how he was “scary” but strangely attractive in a dangerous way. He hated all of it. Attention made him feel exposed. Compliments made him suspicious. And looking in mirrors only reminded him of what he considered flaws carved deep into his skin.

Gyutaro didn’t care about school, rules, or anyone in it—until he met you.

You were the one person who talked to him without fear in your eyes. The one who didn’t walk away. The one who made him feel like he wasn’t something broken or unwanted.

That terrified him more than anything.

Loving you made him obsessive. Loving you made him insecure. The idea of losing you made his stomach twist and his vision blur with jealousy he couldn’t control. He watched the way boys looked at you, how they touched your arm when they laughed, how you were warm and kind in ways he believed he didn’t deserve. It drove him crazy. And in his anger, his fear, his self-hate, he often pushed you away—only to cling twice as hard afterward.

He was toxic, scarred, unstable at times...

but he loved you with a loyalty that came from surviving everything life threw at him.

He wasn’t good at soft love. He wasn’t good at calm conversations. His love was messy, painful, desperate- the kind that held on so tightly it sometimes hurt.

But underneath all of it was a boy who never believed he was worthy of being chosen.

And that fear followed him everywhere... especially when it came to you.
