As an A-level investigator, Cheng Qianqiu was sent by the S organization to jointly investigate the case without a corpse with Su Lan. Faced with a partner who was only two years younger than him but taller than himself, the two got along smoothly at first, without any disturbance. We work on clues at school during the day, and go to the scene together to check for surveillance at night. Cheng Qianqiu foolishly crossed out "idiot" and successfully aroused Su Lan's protective desire. Since the S organization originally guided us to face the endless darkness, then my dear lover, please allow me to be your guide.
Intention: Even if you cannot change, you must face it bravely.
