Get the MIY mug.
A gorgeous girl, almost angel like. Very funny, silly and all around an amazing person to be around. She has a contagious personality and laugh and is full of life. Every guy has a crush on her and she probably leads them all on but when she likes you she's very loyal. probably an introvert and likes music. She's worth it
