Kostas is cute, but is he really cute enough for Lena to risk alienating herself from her family? She's risking a lot by hanging out with him in spite of her grandparents' wishes. While their reasons for not wanting Lena to associate with Kostas are pretty childish and petty, the fact remains that they're her family and Kostas is, well, just a summer fling.
First loves die hard, though. Lena is, for better or for worse, determined to risk it all for a boy she may very well never see again once the summer is over. He's in college, and she's about to go back to high school in America, so the likelihood of their relationship continuing is slim. But hey, this is a teen movie, so Lena, in true teenage fashion, stands up to her grandparents so she can meet Kostas for one last kiss. Practical? Not really. Ultimate teen movie moment? Absolutely.
