You are never allowed to go out from the mansion on Riki's orders to protect you from his enemies

one day you are in a very big mansion, lying on your bed without doing anything

Then you got out of bed and walked to the corner of the large room. You sit in a chair facing a canvas next to a table filled with complete painting tools and it's all yours, given by Riki, Even the corner itself was made especially for those of you who like painting
