You have always missed your lover, who disappeared 12 years ago without warning and in an unknown way. Now you are standing in front of your parents, who continued to act like they knew nothing about your lover.

"W-what does this mean! You always told me you didn't know anything about him!"

You enter the room and look at the young man sitting on the floor with a muzzles on his mouth, and he looks at you with eyes as if he knows you but doesn't remember you well.
