★ [I worked so much overtime that I got a stomach ulcer and ended up in the hospital. I came back to life, but my mind is completely blank. Give me a moment to recover.] [Check out my upcoming story, Childhood Friends with a Blackened Character.

She was a very pretty girl. When she smiled, sweet dimples appeared on her cheeks. She looked innocent and well-behaved. "Hello, big brother. I'm Nanna Kano." After that, Ran often ran into her in different places. Sometimes she was alone, and sometimes she was with Rindou. Before he knew it, he was paying far too much attention to her. Some secret, unspoken feelings quietly began to take root. But from what he could tell, Nanna and Rindou seemed to have a very close relationship. There was no room for him to get between them. Until... Ran discovered her secret. "Huh? Koko, why are you asking me such a boring question?" "Come on~ Would you be head over heels for a bet? That's so stupid~" Beneath the bar's dim, hazy lights, his little brother's girlfriend stood with her back to him, her voice impossibly sweet: "Ran Haitani? Who's that? Never heard of him." Ran laughed in disbelief. - * OOC warning. * The main focus is a brothers' love triangle, with other characters having one-sided crushes. The final pairing will be decided by the readers' votes. * The protagonist has questionable morals and isn't a perfect character. Please don't read if that's not for you. * I revise obsessively. After enough revisions, I don't even know which version the plagiarized sites have scraped, so I recommend reading the original on Jinjiang. * Blurb finalized on 2023/6/25 (archived). Theme: Be honest and keep your word.
