Everyone’s shocked that he’s apparently given up the Hinata Inn, his whole life, for the sake of love…until his grandma enters, clapping. She explains that the “marry one or lose the inn” ultimatum was a test; she wanted to see if he’d callously destroy the happinese of several people for the sake of his own. Since he’s proven his compassion and decency, she’ll permit him to keep the inn, and everyone can stay. Much rejoicing and a huge party. Later, he has fantastic, explosive sex with all of them.
