I'm not entirely sure as I haven't read it in detail. But generally, it might be about a relationship that begins with a kiss and then unfolds various romantic and perhaps challenging events as the story progresses.
Since I haven't read the 'it started with a kiss novel', it's hard to say for sure. However, in such a novel, there are likely to be two main characters, perhaps a young man and a young woman. The male character might be charming and a bit of a risk - taker, while the female character could be more reserved but has a strong will. Their personalities would play a big role in how their relationship, which started with a kiss, develops throughout the story.
Well, it might be about the continuation of the relationship that started with a kiss. Maybe it shows how the characters face new challenges and how their love endures or changes in 'the last kiss' scenario.
Most likely the main characters would be the ones from the original 'it started with a kiss' series. They would be the ones whose relationship started with that kiss and are now facing 'the last kiss' situation.
One common theme is also the exploration of relationships. How that one kiss affects their relationship, whether it's a new start or a complication in an existing relationship.
The friends of the main couple can also be great to focus on. They can add humor, support, or even create some conflict. For example, a friend who is always teasing the couple about their relationship can be a fun addition to the fanfiction.
In some fanfictions, there might be additional side characters that play important roles. These could be friends or family members of the main couple. They might influence the relationship in different ways, like giving advice or causing misunderstandings.
One interesting plot could be the main characters facing new challenges in their relationship, like dealing with long - distance issues. Maybe one of them has to move away for work or study, and they struggle to keep their love alive.
You could also focus on a side character's perspective. For instance, a friend of the main characters who has always secretly liked one of them. This character could try to interfere with the relationship in 'it started with a kiss' in the fanfiction, creating a lot of drama and tension in the story.
One interesting aspect could be the unique interpretations of the characters. Fanfiction often takes the original characters from 'It Started with a Kiss' and puts them in new and unexpected situations. For example, it might explore different relationship dynamics or character growth that wasn't fully explored in the original work.
