Lin Sui'an has a secret crush on Zhou Yanzhou, but no one knows about it.
When he restrained himself and showed dignity, she was humbled and moved; when she withdrew, he lost control.
If you hide your secret love for too long, your heartbeat will expire.
Zhou Yanzhou later realized that when he waited for her to look back, she had already stopped looking back.
Intention: The heartbeat of adults is restraint
