Ok so I LOOVE episode 18 but can I say that, for as much as I love Bong Sook being the sweet summer child of happiness, the epicness of his parents and their combined genes just make me laugh. Mom's a genius in her own right but combined with enhanced super senses, she is almost unstoppable. Dad's an assassin with a heart of gold who plans everything and tries to kill no one, and they made the happiest, kindest baby boy who's always happy and never tries to hurt anyone.
