Love Stalking! is a single-volume manga that collects four short stories by Kanae Hazuki. The title story sets the tone with a tense romantic thriller premise. The second story, Jumping to the Wrong Conclusion, centers on Noe, a girl known for her cute appearance who is popular with boys who only see her as a friend. Underneath that exterior is a tomboy who desperately wants a real boyfriend. When she finally develops feelings for Touji-kun, she discovers he already has a girlfriend. The third story, End of Summer, follows Yuki, a high school student overwhelmed by her parents' constant pressure to study. Feeling suffocated, she runs away from home at the start of summer, leaving a note that she will return by the next term. She ends up living with a classmate and his older brother for a few weeks, experiencing a brief escape from her routine. The final story, Doing the 180, features Wakana, whose long-distance boyfriend Nobuyuki misses her so much that he transfers to her school and moves nearby. Wakana is overjoyed but becomes so flustered and embarrassed by his sudden presence that she inadvertently acts cold and dismissive, conveying the opposite of her true feelings. Each story explores different facets of young love, miscommunication, and the complicated emotions that arise in romantic and personal crises.
