This handsome boy is Ray, a student from United States who also works as a model quite often. I'm sure you have seen him in large ads from a travel clothing brand, for example in the MRT (you can see it below).
I spotted Ray in the Zhongxiao Dunhua area. He said he sometimes goes there because of all the restaurants and shops, as the store from which he carries a shopping bag, JUICE Taipei (you can check their website here). Ray was wearing sunglasses, a Chinese button shirt in light blue from Clot, grey jeans, and total black Converse.
