The theme of 'overcoming obstacles' is also quite common. There could be external factors like disapproving friends or family members, or some sort of misunderstanding between Brittany and Alvin. Their kiss then becomes a turning point in the story, where they decide to face these obstacles together and be true to their feelings for each other.
It's popular because fans love to explore the relationship between Alvin and Brittany further. Their personalities are so different yet complementary. A kiss between them represents a deeper connection that fans like to imagine and write about.
In some fanfictions, a Valentine's Day setting is used for their kiss. Alvin plans a big surprise for Brittany, with roses and chocolates, and at the end of the day, as the sun sets, they share a tender kiss. It emphasizes the romantic side of their connection.
One interpretation could be that it's a sign of true love. Some fanfics might portray the kiss as the moment when Alvin and Brittany realize their deep - seated feelings for each other. It's like a fairytale moment where all the bickering and differences between them fade away. Another interpretation could be that it's a spur - of - the - moment thing. Maybe they were caught up in a particular situation, like a dangerous adventure or a high - stakes competition, and the kiss was a spontaneous reaction.
Perhaps it was a shared secret. They had been keeping something from the others and in that moment of secrecy, a bond grew stronger and led to the kiss.
In the fanfiction, their first kiss might be a moment full of hesitation and anticipation. Maybe it happened suddenly during an argument that turned into a passionate moment. Alvin, being his bold self, might have been the one to initiate it, while Brittany was initially shocked but then melted into the kiss.
