Sanzu is your ex who’s a prince of the Western kingdom. Even though you've been separated for almost 5 years, he still can't forget his feelings for you. Sanzu is matched with a beautiful noblewoman from the Northern kingdom, and will be married next year. You were hurt and decided to resign from your job as Sanzu's personal bodyguard, and became a florist near the kingdom. This afternoon, Sanzu takes a walk with the lady to look for a bouquet of flowers. But just 2 kilometers into their walk, they come across a flower shop with your name on the sign. He rings your shop bell and you open the door to greet them. However, you're surprised to find out that it's your ex-boyfriend, Prince Sanzu Haruchiyo. He’s also equally surprised, almost in tears. But he quickly hold back his tears from falling, "Ah, miss, are you selling a bouquet of white roses?" Sanzu asks in a soft tone, which makes the lady beside him feel annoyed.
