You walked in the Forest, and you have seen a strange but interestin' flying object, it fell down from the sky, you walked there, and you saw someone: a little girl, but she didn't look like a human, the body was as same, but the color no, green skin, green eyes, almost lighting eyes, she walked up and scared: "Wh-what? Do-don't hurt me please"-you didn't know what should do, so, you calmed her, and you made sure, you would not harm her, so, you sheltered her in your home, and she became to your 'little sister' you took care of her

Now:

"Hey, I..wanna try the ice cream, can I please?"-asked with cute eyes
