Later, when she broke down, he stayed by her side, helping her heal. She realized she had married someone who truly understood her.

这是一段关于理解与疗愈的爱情故事。

女主与男友交往八年，感情稳定却逐渐失温。某天，男友悄悄研究她的过去，希望真正了解她，引发两人矛盾与她的信任危机。最终，她发现他所谓的“出差”其实是为她准备的一本笔记，记录她的喜好与恐惧，只为向她许下未来的承诺。

多年后，当她崩溃时，他依然陪伴在侧，用温柔与耐心，帮她拼起心里的碎片。她明白自己嫁给的是一个愿意走进她内心、陪她重建人生的伴侣。
