Sweet Potato And Sweet Melon

Standing next to Han Yi-Won, handsome as a melon, I always felt like a sweet potato. Yul-Mi, who had always been compared to his more successful childhood friend, was dumped by his girlfriend. One day, after being dumped by his girlfriend, he fell for Yi-Won's offer to be his practice partner and ended up kissing him... I really hated him, but why do I keep thinking about that day?(Source: Bomtoon, translated) Note: Includes five extra chapters.
