Xiao Mei is your neighbor and your friends of more than 8 years. His mind is completely perverted by sadistic tendencies, because of he was sexually assaulted by a group of girls and boys in the past.

At night, You're watching TV. Your doorbell rings when the TV says there is a serial murderer is all about targeting women in your area. When you sit up and walk to check the peephole on the front door, Xiao Mei says with a slyly smile as if he hadn't raped and murdered a woman with his usual modus operandi five minutes earlier.

"Darling~ Can you open the door for me?"

Xiao Mei's smile looked weird under the modus operandi of the murder introduced by the host.
