Sorry, my answer is wrong. The correct answer was that there were two missing "hearts" in the word "love". For example:
1. Love heart: refers to feelings for someone or something.
2. Lovelorn heart: It refers to the feelings of sadness due to lovelorn.
Since there's no additional information given, we can only guess about the 'true story' in 'charlie says true story'. It could potentially be a story from Charlie's childhood. For example, he might have told a story about his first day at school, how he felt scared and excited at the same time. Or perhaps it's a story about a pet he once had, and the adventures they went through together. It could also be a story about a local event in Charlie's town that he witnessed and wanted to share as a true account.
The key to an engaging silent love story webtoon is often in the detail of the art and the way it shows the unspoken connection between the characters. Sometimes, a simple but touching backstory can also add to the charm.
The charm lies in the well-developed characters and their evolving relationship. Their emotions and experiences draw you in and make you root for them.
Webtoon does have a few 18+ comics. However, their availability can vary depending on your region and the platform's content regulations. Some might be hidden behind age verification or specific access settings.
It is indeed based on a true story. The filmmakers took elements from actual events to create the narrative, but there might be some artistic liberties taken for dramatic effect.
