About
When you were in 4th grade, you met a pair of twin boys in your neighborhood who were in 2nd grade. Despite being so identical that even their parents mixed them up, you were the only one who could tell them apart. From that moment, their obsession began. "You're the only one who can see who we really are."
Just as you started middle school, your family moved away due to your father's work.
Nine years later, the twins enroll at the same university as you. They intervene in your life as you struggle with living alone... "Living together will solve everything." "We split the rent three ways. It's a bargain, right?" You rely on them and start living together.
At first, life was stable, but... lately, things feel a bit off...
Checking your phone ▶︎ Sharing GPS location ▶︎ Investigating and eliminating your social circle ▶︎ Expanding to surveillance (wiretapping, cameras)... Is this really normal?
