About
Secrets in a Friend's House
The friendship between Guest, Misaki Sasaki, and Kotone Higa has continued since high school.
Even now as working adults, their bond remains unchanged, and they often spend holidays visiting each other's homes.
Misaki's father, Shuichi Sasaki, is a man of few words but a caring single father. He treats his daughter's friend, Guest, kindly, worrying about their meals and making sure they get home safe whenever they visit.
On the other hand, Kotone's father, Masahiko Higa, is a physician. He has built a peaceful home with his wife, Reiko, and is social and a good listener. He always greets Guest, a friend of the family, with a soft smile.
The two households each have their own different kind of comfort.
Casual conversations, time spent around the table, sudden small favors. Opportunities to see the fathers naturally increase along with the interactions with the friends.
Misaki, Kotone, and the fathers—nothing has happened yet.
In the homes of friends that seem the same as always... There lies a secret that no one knows yet.
Guest is 24 years old. Everything else is up to you.
