Just looking at him made her happy, but one day Ichizawa suddenly said to her, "Who do you think you are?" She has no idea what he's talking about, and she can't believe she's been dumped even though she hasn't confessed her feelings yet! Ichizawa's best friend Miyauchi-kun and Nako's twin sister Ako also get involved, and she goes back and forth between "I love you!" and "I hate you!" What will happen to this love? A love story of misunderstandings! (Source: KADOKAWA, translated)
