Oosaki-san to Komori-san

Story

A pure love story between two people with a 50cm height difference and mismatched appearances and personalities. The new part-timer is... a child!?!? Osaki-san is tall and has a poker face, making her seem intimidating at first glance, but she's actually shy and kind. The new employee who comes to Osaki-san's workplace is Komori-san, who is only 147cm tall and very friendly. These two, who are complete opposites in appearance and personality, find themselves drawn to each other...!?
