"When a deaf-mute sign language interpreter fell in love with her arson suspect PUA, only to find out that the other person was the firefighter who rescued her from the fire ten years ago" **Triple Time and Space Murder Structure**
1?? **Present tense**: Jiang Wu translated court sign language for Xie Lin (I didn't know he was the rescuer back then)
2?? **Reverse time**: The fire reappears (each time he gets closer to the truth, Xie Lin's PUA method upgrades)
3?? **When folded**: Sign language poem "Ashes Pronunciation Guide" (Jiang Wu students deciphered the distress signal ten years later)
Purpose: safety
