Before they knew it, they had started seeing him as more than a friend, but they thought that if it meant the relationship would break, just being able to stay as they were was enough happiness. Then one day, Kiyuu confessed. Just as they were about to weave words of rejection, another self whispered in the back of their mind, "Isn't this an opportunity?" Before they knew it, they had said yes.
