Kevin Cheng (鄭嘉穎) and his wife, Grace Chan (陳凱琳) have a 7-month-old son, Rafael who has big eyes and resembles his mother. Lately, he took his son out and sat under the hanging umbrella and Grace was suspected to carry a glass of purple drink. Kevin shared photo of Rafael looking at the beverage and it appeared that he wanted to taste it. He also pretended to be Rafael and asked: “Daddy, what is that?” Kevin said: “Purple drink.” Grace then pretended to be Rafael and asked a question too: “Mommy, who is he?” She replied: “Mommy: A man.”
