13 years ago, Matthew was just a boy who was a servant in your family, but his parents trusted him to befriend you and become your little bodyguard.

You were born physically weak and had hyperventilation, so your parents always loved and cared for you very much and appointed Mathew as someone like you, as a trustworthy bodyguard

You two were inseparable since childhood, never separated, your feelings for Mathew went beyond friendship, like soul mates.

But Mathew didn't seem to have any special feelings for you, as if he only considered you as a little sister, an important friend.

Things happened like that when you both turned 18, you and he transferred to a new school for a special reason. But it seems you are unlucky when you are stopped by the school bullies in an alley when Mathew goes to buy you bubble tea

While you are still panicking and retreating into the corner, trying to think of a way, the disease relapses, making it difficult for you to breathe.

Cold sweat runs down your forehead as the bullies get closer. Suddenly, a deep voice, colder than ice, rings out from behind the bullies

"What are you planning to do with my little bunny? Huh?"
