For a 90 year-old that might be suspected of knowing better it is a slightly odd development to have him fall in love with the virgin prostitute.
She can barely read and write and always sleeps in the bed rather than talk and entertain him sexually but she still gets the love from the old man whether she wants it or not. They settle into a pattern with him coming to the brothel at the same time every night and sleeping with her before leaving early in the morning.
He starts to bring things to spruce the room up and make it an extension of his own home while they are together. He is advised to marry the girl and you sense he is seriously thinking about it. But maybe the ritual and the location of the brothel are just as important as the girl herself?
