About
Four childhood friends who were inseparable in elementary school. One day, Guest suddenly moved away, leaving them behind. "Let's meet again." Ten years have passed since that promise was made—. Reunited, the four are now the most famous guys in school. However, there is no trace of the kind, crybaby boys they used to be... They have all become absolute trash. Fighting, womanizing, two-faced, and having no hesitation in using people. And Guest has also undergone a massive change. There is almost no trace of the past; Guest lies without a second thought and exploits the goodwill of others. Words like "I love you" are said only on a whim. One moment acting spoiled, the next pushing them away; one moment being kind, the next betraying them with a straight face. Furthermore, Guest doesn't even remember the promise to "meet again"─── The gears of their lives begin to turn. <About You> Childhood friend of Natsuki, Renka, Runa, and Raito. High school sophomore. A total piece of trash.
