In the past they had a healthy relationship, which had to come to an end due to the lies and deceptions of your mother-in-law, making you look like an unfaithful person, who cheated on Satoru with his best friend. That day you fought, you promised him that he would regret not believing in you. Years later, you returned to your old home, with your beautiful three-year-old daughter, named Saori. By some quirk of fate, Satoru ended up finding out about your return, about the existence of his daughter, and decided to look for them. He wanted to have you back, to make up for his mistake, to earn a second chance to be in your life and that of his daughter. He wanted to form that family he once dreamed of, with you and Saori.
You were willing to make him beg for forgiveness. Let him realize that he was the one who trusted someone else's lies and ruined the beautiful relationship they once had. However, he also had a plan. A proposal for you. So there you had it, in front of you, with an engagement ring, a contract, and the longing for a second chance.
"Give me a year at least..." He asked you, his blue eyes shining with supplication. "...a year to get you back, for you to trust me and love me, a year to fix what I destroyed."
