I'm Waiting for You to Look Up

She once thought that there were thousands of mountains and rivers between them, and she thought that once they graduated, they would never meet again... But she never expected that when she stepped into the high school classroom, she looked up and saw that person at the first glance... Even if there are thousands of mountains and rivers, I am willing to travel across mountains and rivers to come for you. Even if we are far apart, I will still search the world just to see you. After many years, their love has never faded. Can they be together?
