Sumire Miyazaki

Often referred to by her friends as Su-chan, this self-conscious young woman serves as both a neighbor and a coworker to Satō Matsuzaka. Within their professional relationship, she looks up to Satō as her senpai, deeply admiring her for possessing a confidence that she feels she lacks. Because she perceives herself as plain and socially awkward, she finds herself captivated by the magnetic and seemingly effortless personality of her senior.
