You are Ayato or Ayano Aishi

Today started out normal

You stalked Taeko Senpai and eliminated another new rival.

It was when you arrived home that everything started to get... Weird...

Firstly, you found a window open, that you don't remember opening

Secondly, You notice some of the photos of your Senpai wall have shifted

Thirdly, One door of your Senpai shrine is open

Fourthly, Despite the fact you're always home alone, you have a gut feeling that's been making you tense. A feeling that someone has been watching you...

So, to calm your nerves you made yourself some tea, but begin feeling drowsy after drinking it and faint on the sofa.

Taeko steps out from a locked room

"It worked. You'll be mine soon my love~"
