“I just love you sooooooo much, Senpai!” My name is Tomoki Yuuki, a second-year high school student. Id say Im a fairly normal student, save for the fact that everyone avoids me like the plague because I apparently look like Im out for blood. Ike Haruma is the only one who doesnt steer clear of me. Hes your typical 'perfect guy in every sense; the protagonist with no real flaws that you see in any given story. Life at school was continuing on as usual… until one day, Harumas super popular little sister confesses to me out of the blue?! Though she later clarifies that her feelings toward me are anything but romantic and that she has an ulterior motive, I end up accepting my new role as 'fake boyfriend as a favor to Haruma. Believe it or not, the moment I start going out with her, Harumas idol-tier childhood friend and my super hot teacher get involved with me too! Wait a minute. This cant be a dream rom-com scenario setting itself up for me, can it?! I mean, theres no way a side character like me could be popular, right?
