[Two male protagonists, campus novel]
After the rain, the afterglow of the sunset slowly fell. It fell on a moss-covered sycamore tree, lighting up the way in and out. There are two people under the tree, one is standing and the other is squatting. The breeze blew slowly, and the leaves fell lightly, interrupting the silence between the two. One person raised his head and asked: "You said... What if I don't come back?" The other person was stunned for a moment and smiled: "Then I will wait for you! No matter how long it takes."
At this time, the sound of people preparing to check in and board the train could be heard from the train station. The man who was squatting on the ground stood up and walked in front of the other man. He raised his hand and gently took down the sycamore leaves. He walked to the train station and waved: "Don't worry, one day we will meet each other and say goodbye to the little star."
