Shujinkou no Osananajimi ga, Wakiyaku no Ore ni Guigui Kuru

There's a guy at my high school who's like a rom-com protagonist. He's completely unremarkable, yet for some reason, he's constantly surrounded by beautiful girls, he's an absolute anomaly. I was killed by that guy's rom-com. I was condemned for a crime I didn't commit, lost everything, and took my own life. But then, a miracle happened. I found myself back on the morning of my first year of high school entrance ceremony two years ago. In this miraculous second chance at life, this time, I definitely won't let that rom-com...

"Kazuki Ishii-kun, I love you. Let's get married."

What!? The childhood friend and main love interest of the protagonist, Hidaka Mikoto, confessed to me!!? Even though she's known as the "Ice Empress" in our class, for some reason, she's being super assertive with just me...! Hold on a second, I'm not the one you're supposed to like!?
