Clara, the foster daughter who was secretly not the true heiress, harbored a secret love for her adoptive older brother, Ilya. Mistakenly believing that only by confining him could she keep him, she locked Ilya, who suffered from emotional addiction, in the villa's basement. Misunderstandings between the real and imposter heiresses, along with family conflicts, ensued. Heartbroken, Clara left. Ilya traveled thousands of miles to pursue her. The two resolved years of misunderstandings, finally letting go of their obsessions, and held a grand wedding with the blessings of their entire family.
