New series by Tsubana, the author of Wakusei Closet. There is a phenomenon where people who have their hearts broken completely disappear. The protagonist is Hime Ayaka who is the most popular girl in school. As such, she is a frequent target for confessions. She has turned down everyone who has confessed to her and caused them to disappear. Yet, there is seemingly no end to the boys eager to shoot their shot. So her friends came up with a plan to put a stop to it.
I don't know what the snail game is and google didn't help so I'm just going to assume it's some weird shit Tsubana made up. Maimai can mean snail though.
