I was rejected by my childhood friend who is a Russian half, and being a bullied introverted guy, I was feeling down in the park when a mysterious black-haired pure-hearted beautiful girl advised me to become cool and show them what I'm made of, so I decided to change myself.

"Please go out with me!" "I'm sorry. I can't date you right now." Autumn of first year in high school――I, Sakuraba Itsuki, am the embodiment of every unpopular element you could imagine: ugly, fat, short, bad at studying, bad at sports, socially awkward, friendless, and bullied. I mustered up the courage to confess to Kagura Arisa, my childhood friend and the only person I knew at school. However, the result was a complete rejection. She had gone to Russia when we were in elementary school due to her parents' work. We used to play together often as children, and she was incredibly kind and a good person. When it came time to enter high school, she returned. But...the girl I reunited with...how do I put it...had become unapproachable. Still, I wanted to convey the feelings I'd harbored since childhood, so I confessed...but life wasn't that kind to me...haha... While thinking about such things and sitting alone feeling depressed in an empty park, a girl approached me and started talking. She was a girl who embodied purity itself, and for some reason, I, someone with social anxiety, felt no wariness toward her. "Did something happen? If it's okay, I'm willing to listen." "But...I'd be troubling you..." "It's no trouble at all. Actually, it would bother my conscience more to see you so depressed and just say goodbye without doing anything." I told the girl sitting beside me that I had been rejected by my childhood friend, and she listened quietly. "I see. Then here's my advice: just show her up." "Show her...up?" "Become cool enough that she regrets rejecting you. Become strong enough that you won't be bullied anymore." "Cool...strong...there's no way I could..." "Why are you deciding that without even trying? I don't know the cause of your self-deprecation, but isn't it because you give up without trying that you're in this situation?" ...She's right. She's absolutely right. I want to become such an amazing man that Arisa regrets rejecting me. I want to become so amazing that I can't be bullied by Kisaragi anymore, being called a white pig and all that. I'll do it...I'll do this! I...will change! This is a story of a male high school student who was rejected by his long-time crush, struggling to transform his miserable self and find happiness.
