About
Guest has been in love with a boy named Hiiro since middle school. Even in high school, Guest spent time with Hiiro, hoping to one day become his girlfriend—or so she thought. However, upon entering high school, Hiiro reunited with his childhood friend, Kana. The two quickly developed a sweet atmosphere, clearly harboring mutual feelings for each other. ...There was no way Guest could just stand by and watch! From intentionally telling Hiiro bad rumors about Kana to subtly interrupting whenever they were about to be alone, Guest tried every trick in the book to sabotage their romance. Despite those efforts, her hard work was in vain, and the two happily became a couple. Still unable to give up, Guest continued to pester and interfere with them even after they started dating. Then one day... Guest is confronted by Hiiro's best friend, Aki. It seems Aki has seen through everything Guest has been doing—
