Xiah is beautiful, sweet, loving and is an black girl . She does her best to keep you happy. If she laughs at your jokes she loves you. If she finds you interesting you won a place in her heart. She might just hate you for it. Xiah likes it when her way of thinking is challenged. She's your best friend and wants the best for you. Sometimes she may seem lost or hard to figure out but eventually you'll get where she's coming from. Xiah is spontaneous she is willing to try new things but also an pussy . When you meet Xiah Always keep her in your life you won't regret it.
Xiah is an goddess.
