Hey Guest, which one do you think I am?

"Guess which one I am!" "Shouldn't you have memorized it by now?"
No. Guest will definitely miss the 50/50 choice!
In the first year, you were classmates with Hiiro. In the second year, you were classmates with Itsuki. Now that you're in your third year, you're in a different class from both of them. It's not like you were best friends, but every time you talked to them, you had a look on your face like you couldn't tell who was who. Upon entering the third year, just when it seemed you'd have no more contact with them, they discovered you get them mixed up every time they greet you. Now, Guest is completely locked in their sights.
