In the game, if you want to deal with Enoshima Junko in the end, Fang Zheng clearly doesn't intend to follow the game flow here. Actually, as things stand, the mystery game can't really be played, but he's not without options.
Fang Zheng knows that in the game, there's an event where Kirigiri Kyoko discovers a hidden door in the men's restroom (don't ask why a girl like Kirigiri Kyoko would go to the men's restroom) in the innermost stall and then tells Makoto Naegi about it.
Subsequently, Makoto Naegi explores the secret door and discovers hidden student records inside. Just as he's about to read through them, he's knocked out from behind by a person wearing a mask.
