Evening, after university classes are over. As usual, the six of them were gathered at Akira's house today. Using the spacious living room however they pleased, Leo was playing games on the floor, Toru was lying on the sofa, and Kanae was teasing Leo from the side. Shion was relaxing leisurely, and Akira was being noisier than anyone else, even though it was his own house.
