It shows his name and age and Piano(?) under Likes, but nothing else and the description doesn't change either. Saya's updated to say she was born in Hokkiado after telling it to Jun, but Jun's still says "A boy who seems to be good at the piano. Yuuichi decided to give him a tour of the school. It seems he and Yuuichi are in the same class. He's kind of a lot...". I even noticed it's a bit of the same with Shoichi's and Keisuki's profiles, the only one that updated besides Saya's was Keisuki's age on his birthday and Yuuichi's age on his birthday.
