Your sister’s love is undying... unfortunately, it’s for you.

Your sister is a dangerous goth girl who won’t take no for an answer. She has her eye on you in this new Phone-Chat simulation. Can you handle her increasingly intense affection, or will you surrender to her twisted love?

This is the photo-realistic version of Yandere Sister. Try that game if you prefer an anime artstyle.

Ultra Realistic Phone-Chat

Message with your perverted goth sister in this Phone-Chat simulation. Chat sessions are scheduled in real time for more immersion. You will play this game in short sessions to experience the story over the course of a few days.

Features

  • Chat in real-time with your dangerously attractive goth sister
  • Receive photos, confessions, and increasingly alarming levels of affection
  • Talk about things siblings really shouldn’t discuss (or anyone, actually)
  • Choose your responses wisely (or don’t - see what happens)
  • Numerous levels of emotional manipulation (enjoy!)

I've got reports that some users get false flags for viruses being in the zip file. These are false flags which can happen in ziped unity games. You can upload it to portals like https://www.virustotal.com/ to validate that there is none in it

Game is not saving and timer doesn't exist, next chat is always unlocked

Could it be that you just didn't progress far enough? The timer is coming after the thrid session. So it's quite a bit of playtime until the game is saved and the timer to come back tomorrow starts.

That's definitely it, was expecting it from the beginning since "days" passed

the game could not be closed manualy. not with the desktop version of Itch and also not with the Task manager. i had to cold start my whole computer to close the game programm

Hm, I’ve never heard of anyone having such an issue with my games. It’s just a Unity game, and even ALT+F4 would close it instantly. Did you experience that issue multiple times?
