Okay, so imagine two kids who were fighting over a toy. They were shouting at each other, and it seemed like they would never be friends again. But then, they decided to talk about how they were feeling and why they wanted that toy so badly. They realized they could share the toy and have fun together instead of fighting over it. This is kind of like what's happening between North Korea and South Korea.
North and South Korea used to be one big country, but they split into two after a war. They've been arguing and even threatening each other for a long time. But recently, they decided to have a talk and see if they can become friends again.
They had a meeting, and they talked about what they wanted and why they were so angry with each other. They also agreed to stop doing things that were hurting each other, like testing missiles or shouting at each other on loudspeakers.
They even had a big ceremony where the leaders of both countries held hands and walked together. They said they wanted to work together to make the Korean peninsula safe and peaceful for everyone who lived there.
They still have some problems to work out, but they're trying hard to be friends instead of enemies. It's like those two kids who decided to be friends instead of fighting over a toy.
