Would there be a separate Koito route by any chance? ๐๐ I want to date him too without having KoiTsuki be related in it. So far the game looks wonderful and I am interested to play ๐
Unfortunately, Koito's content does not include going on any dates, and the way the game is written, he and Tsukishima are friends, so you would have to actively not speak to Tsukishima at all in order to not get any of those options. Koito mainly serves as a source of gossip in the game to give the player hints about things they haven't discovered yet.
