What is 书信体格式?
书信体格式通过信件、日记条目、电子邮件、短信或其他书面记录来讲述故事，而不是通过连续的第三人称或第一人称叙述。它营造出亲密感，让读者能够从个人文献中拼凑出情节。
书信体一词源自 epistle（信）。在小说中，叙事以一组书面材料的集合来呈现：个人信件、日记条目、报纸剪报、电子邮件、聊天记录、语音记录，或社交媒体帖子。每份文献承载着角色的声音、观点与知识空缺；它们共同构成更大的故事。此格式可以使用单一叙事声线（一个人的日记）、多位通信者（来回往信），或一个汇编档案（发现的文献）。因为读者只看到文献所展示的内容，书信体故事往往给人以即时性和亲密感，并自然引入不可靠叙述、时间跳跃以及通过碎片证据揭示的谜团。
Usage example
第四章完全是一系列主角与心上人之间的短信，随后是一张撕碎的明信片和一则深夜日记条目，解释了这些信息未说出口的内容。
Practical application
意义所在：书信体格式在浪漫题材中极具力量，因为它能够创造情感上的亲密感——读者仿佛是阅读情书或私人日记的知己。在像 Endless Romance 这样的互动、以选择为驱动的应用中，书信元素让玩家影响将写出或收到哪些文档（选择一个回复、解锁一封秘密信、编辑日记条目），使体验显得更具个人化和可收集性。它还通过将经典套路（秘密仰慕者、误传、异地误会）以文物的形式呈现来焕新它们，鼓励在像 #booktok 这样的社交社区中产生可分享的时刻，并引入富有创意的营销点子（粉丝拼接的时间线、发现的消息揭示）。
FAQ
Is epistolary the same as first-person narration?
Not exactly. Both can be intimate and voiced from a character’s perspective, but epistolary is specifically composed of documents (letters, texts, journal entries) rather than a continuous, direct narrative. Epistolary may include multiple authors and fragmented viewpoints, whereas first-person is usually one continuous narrator.
Can modern formats like texts and emails be epistolary?
Yes. Contemporary epistolary fiction commonly uses emails, SMS/chat threads, social posts, and even voicemail transcripts. These digital forms work especially well in interactive romance apps because they mirror how readers actually communicate today.
Does the format limit what you can reveal to the reader?
It imposes constraints — you only show what’s recorded — but that can be a strength. Constraints create mystery, force show-not-tell, and let authors manipulate reliability and perspective to build tension and emotional payoff. In interactive stories, constraints become mechanics: which messages are seen, which drafts are changed, and which secrets are unlocked.
