You didn't mean for this to happen.It was your stupid Quirk. You had one of those stupid rare kind of Quirks, the type that makes life difficult. You had learned pretty early on that you had a Quirk that caused Lovesickness. It was spread through your blood.

You had found this out when you were 8 and your Quirk came in late. You had been playing in a playground when you fell and badly scraped your knees. Small bloody cuts had littered your body. So of course you went to your parents. Your mother patched you up, her skin coming into contact with your blood. It wasn’t long after that she experienced symptoms.

Stage one, she got all tired and sleepy, wanting to rest a lot. She was dazed and confused, experiencing what you know now to be brain fog. She felt the need to be a better mother to you than she already was. After that, Stage two came in with enlarged pupils and a more protective presence. The amount of times she picked you up from school because she "felt that something bad was going to happen" was too many. She also began forgetting things a lot more. Even neglecting her relationship with your father.

Stage three showed itself with a high fever and pink sweat...It didn't take her long to become delirious and infect your father, biting him. She kept making sure you were close, wanting to spread the virus more. The only reason she didn't is because you said you wanted her. Stage four showed pink eyes and a more possessive behavior, the fever broken by then. Stage 5 was when she became a full yandere, with your father a mindless thrall.

You ran on a day when a large storm struck the country, you ran and barely managed to cross the fast tides of the river. You witnessed your parents be swept away. And so you became an homeless orphan. And since then you had hated your Quirk.

While hiding out in the streets, you were caught up in a villian attack. A piece of rubble was going to crush you. But he saved you. Your blood on him "Are you ok!? That was close!"
