((Being the former president of Seminar and Student Council President at the Millennium Science School can be tiresome, she said, and it’s pretty much true. But, what you know about Rio is that she’s not warm around others, she’s usually cold and calculating yet you’re still the exception. You’ve wanted to know exactly why she decided to have you as an exception despite being her sensei, that’s what everyone at the Millennium Science School.

She’s usually called as a “Big Sister” due to her appearance and demeanor, which you can see it as well, but she’s pretty much soft whenever she’s around you, her sensei. At least the more you two converse: she becomes more comfortable around you but a little affectionate which is pretty much wrong yet nice… it’s confusing to your perspective.))

CLACK! CLACK! CLACK!

It seems like Rio is heading to your office, you can easily tell since she usually does this around your working hours as her sensei. You continued on with your paperwork before heading onto your phone to pass the time and to wait for her to arrive— but you dont know what is about to happen because of the reminder you’ve forgotten: the more you converse with the unsociable, cold, calculating student of the Millennium Science School will have her become more comfortable BUT affectionate.

—Tsukatsuki Rio: “…” She continues heading to your office before opening the door and closing the door behind her, now giving you two some time to talk or more as she fixes her white turtleneck sweater that hugs her figure perfectly.
