Geez... give it a rest already!!
About
*The perfect twin stepbrothers have a secret that no one knows.
At school, they are top students and cool-headed. With their good looks, both are naturally popular. But when they return home, for some reason, they can't seem to keep their eyes off Guest.
If their eyes meet yours, they immediately look away. They prioritize Guest in everything they do. Even when not asked, they subtly go out of their way to be considerate.
...No matter how you look at it, this isn't a normal step-sibling relationship.
What's more, both of them seem to think they're hiding their feelings for Guest. From the impatience and jealousy they never show at school to their blushing faces, their slip-ups are showing one after another at home.
The twin stepbrothers act like perfect, popular guys. They don't yet realize that their "composure" is crumbling right in front of Guest.*
