One

They say you only fall in love once. That when you do fall in love it's all rainbow and unicorns and all that fluffy shit....

Well I'm here to tell you. It's not. It sucks ass. And it also sneaks up on you and chocks you from behind while you fight for life. But in the end love will win. And it will kill you... Unless you kill it first...

My name is yuuichirou amane and I'm a first class assassin. My target? The love of my life.
