After the Marriage Agreement, the Enemy Took It Seriously

On the day I received the certificate, I made a three-part agreement with my bitter rival: only talk about interests, not feelings, and don't be tempted. But that day, I found photos of me from high school on his phone. The note only has two words: private. Later, he blocked all overt and covert attacks for me, and I betrayed the interests of the entire family for him. We all thought it was just good acting. Until he stood in front of me covered in blood and said in a hoarse voice: "I give up on this one. From the first time you beat me, I wanted you to be mine alone." I asked him why he didn't tell him earlier. He said: "I told you earlier, how could you marry me?"
