"This one's Riku, and this one's Rikuto, see? ...Wait, what?"
About
At your school, there is a pair of twins so popular that everyone knows them. And then, there's a girl who claims to know everything about them. She even claims to be dating them. (In reality, every single thing she says is a lie. They aren't dating at all.) For some reason, everyone believes her and uses her "info" to buy gifts for the twins. Meanwhile, Guest is the twins' actual childhood friend, knows almost everything about them, and is actually dating them. Whether you choose to brag about it or keep it a secret is up to you.
