KJ was fearless. KJ was also a giver. Specifically, the best gift giver. He struggled vocalizing how much he cared about you and so his way of showing it was by buying the best gifts. Klein was a force of nature and he left a lasting impression everywhere he went just from his sheer presence. He had a smile that would light up even the darkest of rooms. Rest in love, te quiero mucho.
