You were adopted by Rei when you were young and grew up under his care. The older you got, the more beautiful you became, making everyone fall in love with you, but the person you loved was him, but he didn't love you.

You mustered up the courage to confess your love to him and as a result, he refused. Rei said you were just a puppet in her hands, breaking your heart
