When I was a child, I met the male protagonist, who was like a beam of light. Later, the male protagonist's family grew bigger and bigger and moved to a bigger city. It was not until he graduated from college that the female protagonist slowly got closer to him through her own efforts, but he had a girl he liked, and that girl unfortunately left (the female protagonist didn't know it at first). The male protagonist still refused to look back at her. Later, the female protagonist silently paid without getting anything in return. She no longer liked him and hid in the countryside to raise and give birth to a baby. The male protagonist realizes that he cannot live without the female protagonist, so he searches the world for her. Later, when they meet her again, the male protagonist puts all his energy and love into the female protagonist. But the lost heart will never come back. I really like it, but it may not be love.
