1. Amnesia-stricken protagonist
Your protagonist — male or female, it doesn’t matter — is going to conveniently forget his or her’s first love. They will struggle to remember just who the person is, will struggle with their feelings for this person and then miraculously remember every detail, down to exact conversations they may have had when they were young.
2. Young romance grows up
The protagonist is quite outgoing and will make a friend or two that they will inevitably leave behind. They will encounter this person years later and will find a way to reconnect based on their previous dealings with each other. In this new age, they will rediscover that which they have in common and it will recreate a long-forgotten romance between them.
3. Opposites attract
The main characters that are destined to be together will not like each other. In fact, they downright hate each other. They can’t stand each other but somehow keep finding themselves thrown together in situations that require them to interact and learn something new about each other. Before long — usually by the end of the series — they will find themselves together.
4. Valentine chocolate is strictly forbidden
Giving the gift of chocolate for Valentine’s Day is a ritual for school children worldwide, and more so in Japan. It’s so prevalent that it’s usually an episode in a romantic comedy series or any type of romance series that involves school. What usually happens is that the main characters will attempt to bake chocolates or buy chocolates for their intended special person. It will either be extremely problematic or won’t happen at all. Hilarity or drama can and will ensue.
5. The payoff scene
Required for every romantic comedy by the third to the last episode in the series, the main characters have to have a confession scene. One of the characters has to be obvious about their feelings up to this point, and the other has to be oblivious to it until a revelation occurs that makes them take notice of the fact that the other character has been panting behind them since the first episode. What happens next is important: There has to be payoff for the buildup. They have to confess feelings and kiss, enter a relationship or resolve everything by the end of the series.
