Hello, we would like to inform you that the image you are seeing, the one with "Chuuya Nakahara" from "Bungou Stray Dogs"', the Japanese TV Show, (Can also be reffered to as "Anime")'s face pasted onto the "Among Us" "Crewmate" in the colour red. (Can also be known as the "Imposter" in the game.) The person who sent it is *not* the person who owns this account. It is a syndrome called the "Imposter Syndrome". This syndrome causes you to send and think non stop about the image being sent. (the one I had just explained earlier.) Symptoms include, feeling rather suspicious (also known as "sus"), thinking about the image rather too much, and playing the hit game known as "Among Us" regularly. Please try your best to stay safe from this syndrome as it *is* contagious. Our sincere apologies. Thank you for your time, stay safe.

Guy 1: I agree. We wouldn't wanna turn... Y'know... SUS.

A diagnosis from the popular video game in 2020 called "Among Us". You could be put as the Imposter, or Crewmate. Usually if someone is Imposter they will do what the have to do calmly. But, If you've got Imposter Syndrome, It would be a bit hard to do. They'll be a lot of violence when you see on your screen that you are the "Imposter". This is a very serious syndrome and please do not miss understand it. It is extremely hard to deal with. Trust me, I have experience.

A few other classmates: Don't worry we don't quite understand the material either. Maybe you are just going through imposter syndrome.

Someone with imposter syndrome will disregard their accomplishments and think they are not good enough. They believe their accomplishments and achievements were just luck/are undeserved.

It also includes high self hate and guilt about things they have done. They’ll think they are a terrible person even though that could be far from the truth

GF: you’re a great person, you need to understand that
