Melting Flirting Cookie

Han-Byuk isn’t thrilled when his new neighbor turns out to be the cold, aloof Yeo-Min. After hearing Yeo-Min moaning through their too-thin apartment walls and having an awkward interaction the next day, Han-Byuk gets a glimpse of his neighbor with his guard down. He's shy. Cute, even. Han-Byuk decides to double his efforts to befriend his neighbor and, surprised by each other and themselves, they grow closer until the lines of their friendship blurs into something...more.
