Theres No Way A Side Character Like Me Could Be Popular Right

I just love you sooooooo much Senpai
My name is Tomoki Yuuki a secondyear 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 idoltier childhood friend and my super hot teacher get involved with me too
Wait a minute This cant be a dream romcom scenario setting itself up for me can it I mean theres no way a side character like me could be popular right
