I have made this game up and I hope あなた enjoy it.
To play あなた have to pick your bias from boy groups または girl groups and put them into one big group. あなた can give them positions in the group and make a collage to put on your awnser. But あなた can't put boy and girl bias in a group together because the girls go in a girl group and boys go in a boy group so no gender mixing. If あなた post your awnser but happen to get a new bias あなた can either 編集 your post または just post a new awnser.
Hope あなた enjoy
