In the process of growing up, he finds someone suitable for him and is full of youth. 2. <<Search>>: It tells the story of friends who have been together for more than ten years. It involves pure love elements and is also full of youth. 3. "The Barren City of Love": It mainly tells the story of two beautiful girls, involving youth, friendship, love, and many other elements.
