This is a youth story about two high school students with very different personalities who get close to each other, heal each other, and achieve two-way redemption.
The sunny and cheerful transfer student Lin Muyang ("Little Sun") takes the initiative to approach Lin Qixing (Silent "Fog"), who is self-isolated and withdrawn due to family haze. Through daily care and sincere appreciation, he gradually warms the latter's closed heart. In the end, the two teenagers talked frankly to each other in the evening breeze on the rooftop, and realized that each other's personalities could complement and illuminate each other - Lin Muyang's "recklessness" needed Lin Qixing's "gentleness" to catch it, and Lin Qixing's "sensitivity" was also worthy of being illuminated by Lin Muyang's "sunshine".
Purpose: The best relationship is when both parties become more complete selves. Your recklessness is cherished by me, and my sensitivity is illuminated by you. We are not saving each other, but growing together together.
