My Fiance Betrayed Me, I Married His Childlike Brother

Synopsis

On the day of my engagement, I caught Justin Rowe holding hands with his first love, Erica James, under the table. I couldn't take it anymore. I flipped the table right then and there, calling them out in front of everyone. But Justin stayed eerily calm, watching me lose it in silence. Later, I overheard him laughing as he told someone, "The Lynn and Rowe families are tying the knot. This marriage won't be over just because Hannah says so. No matter how outrageous I get, she can't escape me." He was right. The Rowe family rescued the Lynn family when they hit rock bottom, all thanks to their money. The marriage between the Lynn and Rowe families was something set in stone, and nobody could change that. But Justin forgot one thing: he had an older brother.
