When a girl was young, she missed a boy because of her stubborn self-esteem. Later, the girl wanted to save him, but it was already too late. The boy would never look back.
Although the girl later found out her feelings and wanted to save her, she discovered that if someone misses someone, they will miss it. No one will wait for someone forever. Later, the girl didn't know whether it was a liking or an obsession.
Intention: Missing my lost youth and the person I missed
