"O righteous crusaders for truth, if this girl was put in front of you, would you tell her?"
Maybe yes. Along with the fact that her fake father dreams about telling her the truth, but is afraid to do so. So then they can maybe have a real relationship and see each other whenever they want to and not only when her mother pays him to be professional.
Because clearly both have a real connection.
Btw. is he not scared of openl publishing all this? Or does no one in japan reads english magazines?
