Yoko starts living alone after getting a job. Her mother introduces her to an apartment she thinks is "nice," but it turns out to be right next door to her childhood sweetheart, Yuma! After a certain incident, Yoko had suppressed her feelings for him and avoided seeing him for a long time, so this unexpected turn of events leaves her bewildered. However, upon reuniting, she is completely at ease with Yuma, who is as kind as ever, and in the course of their conversation, she confesses that she wants a boyfriend. He then suggests, "How about we simulate it with me playing the boyfriend?"...!? "We're 'lovers' now," he says, showering her with love from scratch at zero distance...! A sweet and frustrating first love lesson between a "cat-like prince" and a "chubby childhood friend"♪ (Source: Bunkasha, translated)
