Jaenan-eun Neul Gyeot-e Issda

Everything seems perfect in Da-Mi Yun's life. Her career prospects look bright, and her childhood crush Ho-Won even moved back to Korea to confess to her. But her world turns upside down when an anonymous letter leads her to a mysterious house, where she ends up trapped for three hours… except in the outside world, a decade has passed and Da-Mi has been declared dead! Can Jae-Nan, the mysterious, surly god and owner of the home, help her navigate this chaos? Why does disaster strike wherever she goes? And why is this unhelpful god having prophetic dreams about them being together?!
