Maverick Spencer, my husband's older brother, sacrifices himself just to save my husband from a car accident. In order to repay him for his benevolence, my husband, Mateo Spencer, decides to move his newly widowed sister-in-law, Lily Shepherd, into our home. Mateo tells me, "Maverick died saving me, so I must repay him for his benevolence. He was the most worried about Lily when he still drew breath. In order to fulfill his death wish, I must let Lily stay with us. "Lily's biggest wish is to have a child of her own. I have no choice but to sleep with her. It's to repay Maverick, you see. Don't worry, Phoebe. Once she gets pregnant, I won't touch her ever again. You're the only woman for me." But since then, Mateo pays more and more attention to Lily. At the same time, he spends less time with me. When I notice the way he looks at me icily, I feel my love for him starting to get snuffed out.

I know I should have kept my distance from Xavier Hathway. He’s my brother-in-law. A man I once barely noticed, now turned into someone impossible to ignore—mature, captivating… and somehow filling every corner of my darkest thoughts. Everything started to fall apart the moment he caught me. After that, there were no more boundaries. No more reasons. We crossed every line—norms, morals, and vows I was never supposed to betray. And the worst part… I don’t want to stop. Instead of walking away, I’m sinking deeper. Into touches that feel wrong, into a desire that should never have existed. The pleasure Xavier gives me is too real, too tempting—until I choose to give in. But I know… something forbidden never ends well. The only question is: who will break first?

On our wedding night, my husband Grayson's sister-in-law, Scarlette, stumbled drunkenly into our bridal suite and threw her arms around him, refusing to let go. "Kayla, my husband died young, and I really just want a child. Please, lend him to me for one night," she cried through her tears, shoving a toy into my hand. "I promise I'll return him tomorrow. And if you get lonely… you can use this to comfort yourself." I stood there, dumbfounded, my gaze shifting in confusion to Grayson, who was already helping Scarlette steady herself. "You're really going to sleep with her?" He avoided my eyes, his tone strangely urgent. "Don't overthink it. She's drunk and talking nonsense. I'll take her back to her room to rest." As he started to leave with her, I stepped in front of them, blocking their way. "Grayson, it's our wedding night tonight. Are you seriously going to walk out with her?" His expression darkened as he pushed me aside. "You're my wife now—try to be more sensible. Don't get jealous over something so trivial." Then, carefully, he guided her out of the room. I wanted to run after him and stop them, but when I saw the deep concern in his eyes as he looked at her, the truth finally hit me. The love this man had for me was no longer mine alone. And if that was the case, why should I cling to a marriage that had already soured? I might as well walk away with my head held high.
