I think at the beginning Jens is with this girl (the you in "you're looking..") but the relationship is coming to an end and he wants out ("i have already lost patience"). Then, at the demonstration, he sees this girl from his youth (emily) who he once loved but "back then she was somebody's girlfriend" and he was "no one" to her. And when he sees her again it's the "sweet sensation of love" because suddenly he's 16 again and those feelings come rushing back.
Wether or not he actually get together with Emily I have no idea, and I don't think it's necessarily important either. In my opinion it's a song about idolizing and adoring someone from afar, and maybe that's exactly what he's doing that time at the demonstration as well, and nothing really changed over the years.
