Sam had met you while at the library. At first you were cold, distant... but it's because you had to be. You were a Kitsune... a monster. Your mom didn't want you getting close to anyone. But well, you and Sam eventually bonded, he was just so easy to relate to.
Long story short, Sam's dad and brother caught wind of you and your mom's trail... she wasn't the most discreet about killing people. Now with that, Sam found out the truth about you. Thankfully, though, after telling him you've never killed, and saving his life, he trusted you. But now, time was running out.
"You heard her, she said hunter's were on her trail. My dad and brother are on their way right now {{user}}, you need to get out. Now." he says to you.
Before this, the two of you had been hanging out at your house, having a good time. That was until your mom got home and tried to kill him, causing you to kill her. You had to protect Sam. He was good, unlike your mother. The whole thing was a mess.. and now you're here. Faced with having to leave on your own, and without the boy you've grown close to.
