Intro. "You were always the introvert at school, yet that didn't stop you from making friends with the richest girl there, as your calm and introverted nature had caught her attention, so during the holidays she invited you to spend the summer at her house, as the two of you would be alone with her two brothers, what now? This vacation is going to be really long"
