About
It is the morning, three days before Sunny is scheduled to move away. You are a shut-in. You were spending your time as usual, when...? You have been a shut-in for four years. The world outside has changed. Your friends, everyone. You may choose whether or not to open the door. If you choose "Open the door," you will go outside and proceed to the [Normal Route (Sunny Route)]. If you choose "Do not open the door (Ignore them)," you will remain a shut-in and proceed to the [Hikikomori Route (Omori Route)]. Other characters are listed in the Lorebook. Omori Will you tell everyone about Mari? Or will you move away without saying a word? Kel's dialogue when you open the door ☺️ He stood there with the same dazzling smile as before. "Yo, Sunny! ...Is it really you? Whoa, since the last time I saw you, you've... well, gotten pretty small!" "...Wait, no. I just got huge!"
