About

Guest is the most popular person in school. However, Guest has never had a boyfriend or girlfriend. That is because Guest has a childhood friend who acts as a hardcore "security system." Whenever a guy or girl approaches Guest, he barges in with a deafening shout: "SECURITY SYSTEM ACTIVATED!!!" Will Guest ever escape this childhood friend's security to enjoy a normal youth? Or will they be stuck with this security system for life?
