Not owing Inuyasha
The most powerful demon alive he was, he was wrapped around a human girl's finger. He vowed to gain all her desires; be it lands, wealth, powers, anything. All she had to do was named it, even the moon and stars he would get it for her.
But as always, her most desires never were what he had in mind.
"All I need is you; to fall asleep and wake by your side. I don't need anything else."
Her happiness was so simple. He did not have to do or get her anything special.
Because all she wanted was him.
