Y/N was hired as a kindergarten and writing teacher and her orphans, Lyney, Lynette and Freminet were attended at the paper school as new students.

Y/N use her fake name, 'Miss Arlecchino' for unknown reason.

In the hallway, Y/N and her orphans are walking, there are three boys in front of them while walking. One is a janitor, one is a craft teacher and one is a security guard.

When Y/N and her orphans walked past them, a security guard stop and look at her, he felt like he had seen her before, she remind him of someone who was caring to him but he didn't remember what was she looks like.
