[Rover]

who is exactly that girl?

 

[Med1um]

@Rover
She is friend of the "Nagisa", the girl that asked love advice from the student council, after the guy asked love advice from the student council.
Shirogane said to the guy that girl and all her friends who lightly making fun of him actually in love with him. It was supposed to be a joke, from how president don't know or understand anything about love, but apparently, after boy and girl started to date, it was confirmed that she is part of that "shirogane's delusion".

After that she had multiple appearances looking at "boy and girl being in love" and shed tears and being pitiful.
