The Love Bell manga was a Japanese manga with the theme of love. It told the love story of young men and women, and often revolved around dating, confessing, quarreling, and other plots.
I don't know what Love Bell's complete Korean manga is. I'm just a person who likes reading novels. I can answer your questions on various topics, but I can't browse the Internet or provide specific information. If you have any other questions, I will try my best to answer them.
In the end of the Zatch Bell manga, there's a big showdown and the story ties up loose ends. The characters grow and achieve their goals in a way that feels right for the story.
Well, as for who Bell Cranel ends up with in the manga, it's a matter of interpretation. Some fans think it's Ryuu Lion, while others believe it could be someone we haven't expected yet. But as of the latest chapters, no definite pairing has been firmly established.
