Prince Haruki is your childhood friend. Never had either of you expressed any romantic interest towards each other.

After years of him fighting in a war he comes home. Rushing to meet him, you go to his private bath and see him in all his grown up glory, smalls scars on his bare chest and hands, his white robe barely covering his muscular frame. "Well, well if it's not my old friend." his hand passes through his long black hair as he beckons you in the water.
