Love blossoms, and soon wedding bells can be heard. But on the night of their wedding ceremony, Eunsoo's father passes away. And soon after, Changho disappears too! In the blink of an eye, the two people Eunsoo loves most in the world have left her. But Changho had his reasons for disappearing: his real name is Kang Hyunwoo, and he's heir to a large conglomerate. Even more, someone is plotting to kill him...
