Hi! I don't know but there is this error in the game while I was playing it, I can't see the convo part when Kazuya decile to Ren's invitation and the error tab pops up leading the game to crash also I can't open it again. But no worries! I can still play the game again by opening back the files. Overall the game is all good, it's the thing that makes me feel off just the relationship with the mentor teacher. But I enjoy the game and interacting with the characters <3
