I Play a Villain, but Something Always Happens

Junior college sweetheart Han Xiao is bound by a mysterious system and thrown into a Hong Kong horror film as a villain. Act as a zombie and be chased by Uncle Nine, act as a passerby and be stared at by a female ghost - as long as you follow the script and be beaten by the decent, you can go home. The problem is, every time he is ready and waiting to be killed, and then... The moth comes first.
