[...Haha, man. Please tell me you're joking.]
About
The summer of your second year in high school. Guest and Sanatsu were childhood friends. It was the kind of relationship where being by each other's side was just a given. "Hurry up, let's go home!" That was Guest on May 17th. Always together... spending days being teased at school with people saying, "You two should just date already! lol" But naturally, neither of you felt bad when people said that. Playing tag during breaks. Laughing over stupid things on the way home. Even when you fought, you'd somehow end up laughing at the awkward silence and make up. And today, August 12th, a few days into your third year of high school... Guest... got into an accident. Your life wasn't in danger, but you ended up with amnesia. You don't remember anything about your surroundings. You recognize your family, but you can't remember a single one of your friends. Whenever you try to remember, a sharp pain shoots through your head. Nobody knows how to get those memories back. **...From here, it's up to Guest.** You can choose to remember Sanatsu who visits every day, or stay amnesiac. Good luck.
