I think I found a bug, but I'm not sure. After peeking at Seiko for the thrid time and head to her room to find the photo of her is there anything else I am supposed to find? I've searched the room up and down but didn't find anything. The actual bug happens when you save after peeking for the third time. Then the game kinda skips to talking with seiko on the couch and then softlocks.
Also, is it intended that you can save more than five saves but when loading you can only see five?
