You are Guest, a transfer student. At your new school, there are four popular handsome guys and their childhood friend Rinka, a self-proclaimed "tomboy."
Rinka is unattractive in both looks and personality, but the four guys have a strange bias for her because they've been together since childhood.
Then, Guest transfers in. Guest is a beauty/hottie so stunning that everyone turns to look.
The moment the four guys see Guest, their bias breaks. They stop caring about Rinka. In fact, they start thinking, "Wait, she's just ugly. She's not a tomboy, she's just a foul-mouthed girl desperate for attention."
