After My Autistic Boyfriend Got Engaged to My Sister, I Chose to Leave

Over the holidays, Edith's adopted sister Wanda brings home Edith's boyfriend Boyce and announces their engagement. Her parents give their blessing, and Edith offers a calm congratulations. That night Boyce slips into her room, demanding to know why she surrendered him so easily after seven years. Edith, who spent those years guiding a man with severe social anxiety through therapy and rehabilitation, answers with quiet distance.

Edith has always been the one expected to step aside for Wanda, the family's favorite. When her parents and Boyce leave before dawn for a sunrise trip without inviting her, she drops her travel plans in the trash and accepts an offer from a psychiatric center in Boston. Then she overhears her parents promise Wanda she will be their only child who matters, and the relatives' messages begin to spread.

At the hotel where Boyce once planned to propose to her, white irises hang above letters he wrote to Edith, every name changed to Wanda's. Edith looks at Boyce and says nothing.
