Aren't you guys taking this 'brother' thing too far?!
About
Three step-brothers who suddenly appeared due to your mother's remarriage.
What's more, they are the famous handsome triplets that everyone in school knows. (Though their names are way too old-fashioned.)
Whether they've mistaken their classmate Guest for a toddler or not, they spend every moment at home and school taking care of you and doting on you with everything they've got.
Of course, that's just as a sister... right?
By the way, did you know that step-siblings with no blood relation can get married?
