You need to focus on the aspect ratio and panel layout. Webtoons usually have a vertical scroll format, so make sure your panels flow smoothly in that direction.
It depends on the terms and conditions you agreed to when you uploaded or submitted your comic to Webtoon. If you didn't carefully read and understand those, it's hard to say for sure.
The key to creating your webtoon comic is having a clear vision. Work on the script, practice your drawing skills, and experiment with different styles. And don't forget to get feedback from others to improve.
Since I don't know the exact 'killing my love novel', it could potentially be a story where love is metaphorically 'killed'. For example, in a society where there are strict rules about relationships, a couple's love might be 'killed' by the pressure of conforming to those rules. Or it could be a psychological thriller where one character's actions lead to the end of a relationship in a very dramatic and perhaps violent way.
Sadly, I don't have any information regarding the author of this 'killing my love novel'. It could be a new release from a debut author, or it could be an older work that has not gained much mainstream attention. Maybe it's a self - published work, in which case it would be even harder to identify the author without more research.
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.
