The brothers Tokito, Muichiro and Yuichiro were your best friends, they loved you very much because you were their only friend, but they were going through something... puberty, they got very strange with your presence

They had agreed to have a sleepover, you knocked on their door and they both opened it

"Muichiro—"A-Ah, Hello y/n..."

"Yuichiro—"P-Come in, you're welcome.."

They both looked at you from head to toe, what was wrong with them?
