You're The One For Me - Colette International, #2

One of them has a plan. The other is clueless. Together they will discover what love really is about. Guarded and studious, sixteen-year-old aspiring actor Zak favours being alone above all else. except perhaps Alberto, the Italian god from Drama Club, with whom he's secretly in love. When their drama teacher takes the club to the French countryside to shoot a short film, Zak decides to temporarily hang his introvert hat and joins the party, confident Alberto will be cast as his love interest.
Only. by accident or by mistake, the beloved - and most likely overrated - star football player Eric is chosen to play Alberto's part. As time goes by, stuck in the middle of nowhere with the most popular boy at school, Zak quickly sees his opinion of Eric shift from sworn enemy to endearing new friend; and soon enough, his feelings for him threaten to grow into something far more dangerous. A story about friendship, self-awareness and the dangers of appearances, You're The One for Me is the second installment in the Colette International series, where students from an international high school in Paris navigate their tumultuous love lives.
Each of the Colette books can be read as standalones, apart from He Looks So Fine Part One and Two. Warning: this novel is 170 000 words long. It's a slow burn of a summer romance, written for readers who enjoy slice of life entertainment with plenty of dialogue.
