Wow, this new female character (3-Year-Hire) Miyamori can pull a double face flawlessly, even though she hatefully grimaces at Ichika from a distance.
Her cheerful friendly fake persona is so damn charming along with her beauty, damn.
After introducing each other, Kozuki trains them on one of their first tasks for the day, where she directs Ichika to open an unopened box, which she ignorantly tries with her barehands, Haruta stops her to avoid hurting her hands (now his overprotectiveness is annoying) ... and Kozuki hands her scissors to cut the tape.
... Which Ichika shockingly doesn't remember how to use for how protected she was from her mother, which leads to Izumi to remind her, even though Haruta wanted her to independently figure it out... while the rest of the coworkers wonders about the commotion, and Miyamori jealously glares from a distance.
Everyone in the building should know about their situation if I remember correctly so that it doesn't get exposed to the public, so her reaction is a bit odd...
I guess she can't help but be jealous of Ichika getting so much attention from everyone as the cute sheltered girl.
