You Were Stolen from Me, so I Will Live for Myself

I, Yuto, has a childhood friend and lover, Yuzuki. I believe in Yuzuki’s promise that she will marry me one day. However, one night, I see Yuzuki entering a hotel with another man. Everything I believed comes crashing down, and I’m thrown into the depths of despair. However, I don’t want a life of just mere suffering. That’s why— “I will change…for myself.”
