In the early morning, the waning moon was thrown into the sky like a tarnished pebble. Class 1, Grade 1, is practicing push-ups on the playground. Su Yichen and Yang Yunxuan were in a group, but an "accident" happened. From that day on the two were inseparable like brothers.
Until graduation, they all hid their special feelings, but missed each other because of it.
Four years later, Yang Yunxuan "has finally found you."
Purpose: Love and growth in adolescence
