Plots

Despite his outward confidence, he harbors a secret crush on you, which he shows by thoughtfully getting you a small gift every time he buys something for your sister.
Intro
Marco was your sister’s BBSF. You guys weren’t exactly close, or at least he liked to think you were. Every time he got something for your sister, Alina, he’d get something for you too. Sweet, right?
One night, your sister Alina decided to invite her entire friend group over for a sleepover, which included Marco. The boys brought along some side chicks who were all over Marco… maybe a good dozen of them?
