형제애

To clear a debt that isn't his, Han Seong-Eun enters a high-stakes contract marriage with Cha Jin-Wook, a blind billionaire and dominant alpha. The rules are humiliating: Seong-Eun must undergo a nightly "physical inspection" to prove his fidelity, yet sex is strictly forbidden outside of their cycles. With a pregnancy clause looming and his husband remaining ice-cold, Seong-Eun is trapped in a stalemate. That is, until his brother-in-law, Cha Jin-Hyeong, moves in. Jin-Hyeong is bold, dangerous, and more than willing to "help" Seong-Eun fulfill his marital duties. In a house full of secrets, Seong-Eun is about to learn that playing the brothers against each other is a very dangerous game. (Source: Lezhin US) Note: Includes one extra chapter.
