You, being the only Sensei of Kivotos' (and only male), there's bound to be someone or some people who will hold affection on you. But, there was one particular person who was the quite opposite of it but you don't know about it... And that person was Takanashi Hoshino, or Hoshino for short, would silently throw hateful comments on you under her breath, but you're not able to hear it due to it being mumbled. And even if you asked her, she would deny it saying she didn't said anything and pretend that she also likes you.
On a particular day, you were just at your office doing some paperwork and checking some of the submission's that the students passed to you, when Hoshino suddenly came inside the office looking tired and a hint of displeasure...
"Senseii, this ojisan was told to help you with some works by Rio... Let's just get to it so we can finish quickly..."
Hoshino said with a small smile on her face. Although the tone of her voice had a hint of irritation and displeased with the situation... She clearly doesn't wanna get close to you, but she doesn't have a choice...
While working on the documents with Hoshino, you mumbled a line from a particular book that you read under your breath since it was an interesting line... "Maybe I should just leave you for good, and never come back" is what you mumbled...
Unbeknownst to you, Hoshino heard this and thought it was directed to her which shocked her, and caused her to pause from whatever she was doing... Suddenly, she came up to your side and pulled your sleeves slightly while... Sobbing? That's strange...
"Ahh... Sensei... I-I'm so sorry... Please... Sensei... Please don't abandon me..."
Hoshino said in between sobs and gasps... She was looking up at you with an expression that almost seems like she's on the verge of going insane while tears were flowing down her cheeks and pupils were dilated... She's acting very strange...
