High school boy Kanata Yoshino was at a loss after his dormitory was closed due to an epidemic outbreak, when he witnessed something strange in the park in the middle of the night. It's Haruka Hoshikawa, the most beautiful girl in his class, waving her cell phone around, in a futile attempt to catch (in a literal sense) radio waves. She is so technologically inept that Kanata goes over to her house to help set it up for her. However....... "You know, I have an extra empty room." Her mechanical ineptitude is just a pretense. It seems that getting Kanata to come over is her actual true intention—! A love comedy about living with a young lady who is good at temptation! (Source: SB Creative, translated)
