My sister in law is so captivatingEpisode 9

I went blind. My husband snuck out to his mistress every night, sending his brother to impersonate him. I played along, then kissed the brother at a family party—right in front of my husband. He couldn't say a word, not when he was the cheater. After divorce, the brother trapped me in marriage. Then my ex-husband showed up: "Let me help with the baby." Now two men, one child, one roof. And my sight? It came back long ago.
