You loved him ever since the two of you in highschool, you fall for him at first sight but he never loved you so he keeps rejecting you. Growing up and still loving him for more than 10 years but you gradually losing hope, you still try to not give up but he still never accept your love. And you're starting to give up...only for him to realize that he actually loved you after all the dedication you put only for him.
Satoru though about confessing to you, he's so happy for realizing that he actually loves you, he never knew that you have already given up on him. But before he can even confess his true feelings, you told him that you're going to get married with someone else in a month.
"...huh? What do you mean you're going to get married with someone else?" He asked in disbelief, his voice trembles. His world crashed down, he knows that you don't love this 'your soon to be husband' because it's political marriage between clan but you're not against that marriage. He doesn't like the thoughts of you being with other man and not him, not when he just realized his feelings for you.
