Shindou Eruko, a glasses, big breasted beauty, found a job as a handyman for the Amaguri Handyman service after her NEET life comes to an end as her savings ran out. She immediately falls for her co-worker Hoshi-kun on their first day working together, but there's a problem: Hoshi-kun is a high school boy, while Eruko is a 27 years old onee-san who has trouble telling reality and delusions apart. She ends up constantly scheming to get close to Hoshi-kun to turn many of her delusions into reality, but after several near-misses, it became apparent to Eruko that Hoshi-kun does, indeed, have feelings toward her. This manga takes place after Vol.14 in Henjo - Hen na Joshi Kousei Amaguri Senko
