My Love Comedy with the Unfallable Beautiful Girl Classmate Is Too Much of an Easy Mode

Synopsis

After returning to my hometown for the first time in four and a half years, I learned a shocking truth at the high school I transferred to. For some reason, I'm supposedly in a long-distance relationship with my childhood friend and now classmate, Kousaka Nanami, who has grown into a beautiful girl. I have absolutely no memory of this, so what in the world is going on, Nanami?! …Eh? You got tired of being confessed to every day, so to keep the guys away, you made up a story about being in a long-distance relationship with me? And you're begging me to pretend to be your boyfriend? I guess I have no choice, I'll play the part of your boyfriend, but only while we're at school──wait, Do our parents believe in this long-distance relationship too?! There's no turning back now… All romantic rivals have already surrendered & both our families are giving us their ultimate blessing!
