I have to admit, it's not the most likely outcome of this comic, but I am going to offer at least one ending for each of the characters. And as Isabel says, the mind is a powerfull weapon. If you so choose, either Isabel or Sayo can come out on top.
In case of Isabel, she will be strifing to become the new head of the office. So taking Stacey's job. Also she is bisexual from the start and she will start dominating female and male staff in the process.
Sayo on her end will contact the hypnotist and have those pesky suggestions removed... after taking her friendship with Isabel to the next level ;)
Voting will start mid February (probably starting 16.02.2022) and will be available for one week.
