Someone who work at Tom&Toms Coffee Saw Taemin and Kai.
(OP as this person, which men original poster, the person that posted this)
OP works in Tom&Toms Coffee The Calypso in Apgujeong. One day during winter, Taemin and Kai entered the cafe wearing hoodies. OP couldn't remember but the two of them ordered either Cinnamon Mocha Tomnccino or Java Chip. There were a lot of cactuses in the cafe, Taemin and Kai played rock-paper-scissors and looks like the loser had to poke the cactus'thorn
