Sono Yokogao wo Mitsumete Shimau ~A Profile Kanzenban~ by Akabei Soft - Adult Sex Game

You start out as Masayuki, a seemingly normal guy who is diligent and hardworking in terms of studies and work. A model student, with only a small group of friends.
Waking up in the morning by his sister, running to school together every day. Talking to your friends and just learning. After that, walking home with his sister or walking around the city.

This is his usual day. A perfectly normal day.

But it won't last long. There are those who still remember who he was before and what he did. His past begins to haunt him.
