It's after you take Sayako to Anna for the pendant and have to meet Kana at the Eversea Town Beach(Basically the end of the content not counting the hide and seek mini-game after talking to Kana at the beach). Instead of going to the beach, go to the Eversea Town Bar(its the building thats next to the entrance to the slums) and talk to Sayako at the top right most table for the scene. There's some other hidden repeatable scenes not in the recollection room like the scenes in the Armor shop changing room and the Abandoned House in the slums. I'm not sure if there's anymore than those.
