Shyness

When Ozu's eyes first met someone's eyes by chance, he looked away in a hurry, which showed his shyness. He was awkward with whomever he met for the first time, looking downward right away. If he had been married, he might have behaved differently. In fact he remained single, you know, he appeared sexy in such cases. Quotes from Yuharu Atsuta
