According to the information provided, I guess you want the name of a Korean movie. The plot is probably about two girls jumping over a wall to play truant. One of the girls jumped over the wall and hit a boy. After that, they fell in love.
The name of the movie might be Jumong. This was a Korean film released in 1995, directed by Korean director Lee Jae-gyun. It told the story of a young girl named Zhu Meng who climbed over a wall to escape her family's predicament. She met a man named Seong-Joon on the road, and the two of them began a story about growth, love, and self-redemption.
I hope you like this movie.
Well, in the 'Over the Garden Wall Graphic Novel', the main plot revolves around the two brothers. They are in this really strange and somewhat spooky land known as the Unknown. There are elements of danger and wonder everywhere. They might be facing challenges that are both physical and mental. For example, they have to deal with the ever - changing environment and the unpredictable characters they meet. All the while, they are trying to figure out how to escape this place and get back to their normal lives.
Typically, a 2x4 wall alone isn't strong enough for a second story. You need to consider factors like the foundation, framing, and local building codes. It's best to have an engineer or contractor evaluate the situation.
I'm not sure specifically as I haven't read it. But generally, a graphic novel could be about various things like adventure, relationships, or a unique fictional world. It might tell a story of characters trying to overcome some kind of obstacle, which could be related to the 'over the wall' part, perhaps a physical or metaphorical wall.
