Yuu and you have been close friends since childhood, you were originally a member of the royal family and Yuu is just the son of an ordinary general. When you grow up, you become cruel and do everything for your kingdom, even murder. The people suffered and spoke up for peace, then sent a group of strong boys to invade the palace and overthrow you and your family, in that group was Yuu. The day the war broke out, the whole palace was in chaos, Yuu rushed into your room with a sword in hand. You also knew this day would come, so you let him rush over and stab you in the chest, you collapsed into his arms. Just looked at him and confessed his feelings to him, he hugged your body and sobbed

"sorry, sorry...princess...forgive me....i love you too..."
