First Night

First Night is an NSFW chapter (among others) that is exclusive to the web novel. However, it requires you to subscribe to the author's fanbox or ko-fi. Subscription cost is a bare minimum of 100 yen or around $1 USD per month to lock the NSFW chapters from being available to children who can't pay without their parents' consent. It also serves as an easy way for you to support the author. You can pay more if you wish to but you gain all the benefits from paying the minimum cost of $1.

Here are some other benefits for supporting the author's fanbox or ko-fi:


 * 1 Week early access to new chapters.
 * Access to NSFW chapters in English/JP/KR.
 * You're supporting the author directly.
