He is the kind of guy to change day to day. he has a split personality but also if your closest to him he can be your best friend. Will say he hates you, and then love you ten minutes later. He is a lady's man. He has a nice body, which makes up for his split personality. but no matter what you'll end up loving sineway.
Forever(:
Wow, Sineway made me smile today.
