The birthday celebration for Prince Alvis begins with his first dance with Lady Erina... and ends with an attempt on Alvis's life. As Alvis slowly recovers, Erina refuses to leave his side. Erina's blossoming feelings for the prince are growing stronger by the day, and as such, she hopes to close the distance between them... But for whatever reason, Alvis seems determined to keep his fiancée at bay. Meanwhile, the investigation into the assassination attempt reveals the perpetrator's possible connection to Lillian — the young woman for whom the former crown prince betrayed Lady Erina. But why on earth would Lillian be involved in the attack...? Unless, of course, the poisoned arrow by which Alvis was struck was not meant for him at all.
