It was the tenth year that my brother hated me. When I was desperate, I ran towards the sea, but met a young heroic spirit full of hope. He wanted to see the current motherland. Moved by my heart, I took him to travel all over the world. I expected to study and work side by side from now on, but he suddenly left me on the way. . . This redemption in the name of enjoying the mountains and rivers together contains many regrets after all.
