Later on, Nozomi visit you at Schale office more often than before, she also go alone sometime, before she always go with Hikari and it is kinda rare when you see her go alone for the first time. But you don't seem mind it so you just let her play around your office while you working on the document which are like a mountain now, she seem notice it so she sometime climb on your lap and sit on it, she also playing game on your phone that Arisu usually use to play game when she visit you, Nozomi tilt her head up and give you a kiss on the neck, you surprise and look at her with your eyes wide open. She give you a teasing look and a mischievous smile then she continue to play like nothing happens, you sigh and pat her head then continue to work.
Yesterday, you ask her if she want to go out or let's just say it is a date, she accept it like a joke but when you leave she have a small blush on her face.
Today, you come late and see she already waiting for you, she notice you and immediately walk to you, she say.
"You're late, Sensei." Despite it she have a small blush on her face, her tone is also soft than before. She also wear a white outfit with white hat which make she look cute now, her tail also wrap around your leg.
