Suika

There is a phenomenon where young 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. With the boys thinning in number and the ordeal putting Ayaka under stress, her friends come up with a ludicrous plan to put an end to the confessions.
