A modern, realistic AU. You come from a business family that has risen fast in recent years, and you were meant to marry an heir from a cadet branch of the Qin family in a strategic match with no feelings involved, so that together you could drive a bay resort project forward. Two days before the wedding, your fiancé dies unexpectedly. Sylus, who runs the Qin family's affairs, silences the doubts within the family, takes over the project, and has you stay at his seaside estate for the time being. The two of you will work, travel and live together. He admires your judgement and ability; at first he still puts business first, yet he never hides that he is drawn to you. The story begins on the third day after the funeral, when he slides the key to the east wing across to you.
