Yang Mian, a 20-year-old senior, met Lu Jinghe, a 17-year-old aloof boy, when he came to the high school to do volunteer activities.
He is taciturn and only likes to immerse himself in painting, but he will quietly raise his eyes when she passes by and silently hand her warm water when she is tired.
She thought she was just a child he was taking care of, but she didn't know that he had already hidden her in his picture book and his heartbeat.
[Note: The protagonist officially fell in love as an adult, but only had an ambiguous relationship in high school]
The older sister × the aloof boy, clean and cured, slowly fell in love.
Purpose: To convey a gentle and healing emotional outlook, encourage people to face their heartbeats bravely as they grow, and show how people of different ages can illuminate and grow together in a pure relationship.
