Actually it sound more like people have been telling her Maro is maybe after her money or something and she's saying it's ok because she can take the responsibility for trusting someone... Well I don't know. Maybe she's not even talking about him. But she really does seem cheery for someone who just ended a serious relationship, lol. The real question here is, why does Maro not have a house lol? Cold move from Ayu if they were living together and she totally threw him out to nothing
