System

Game Start
Where the player accesses story mode.

The story has 8 chapters in total. Each chapter is split into several stories that may lead to branch ends, but there is only one True End that allows further progress into later chapters; each story requires 1 Ticket to unlock (noted that the player can access up to Chapter 2 without Tickets).

Gameplay

 * Novel: details the story progress and the interactions between characters.
 * Searching: finds items in certain locations, sometimes involving moving between locations and inquiring characters for information.
 * Questioning: uses discovered items to discover the character's background before arriving at the hotel or find contradictions in the character's statements. The player is usually allowed 5 attempts in total; when the attempts runs out, it is Game Over. The attempts depend on the part of the story, usually when it's a crucial part, there are less attempts.

Stages
Where the player accesses available chapter structures.

When the player reaches a new chapter, its chapter structure will become available in Stages, revealing the pathway to True End and branch ends. Consequent stage titles will remain ????? until the said scene is cleared.

The player can use coins to unlock Rereading, which allows reading cleared chapters without Tickets and provides hints to access other branch ends.

Gacha
The Gacha has a morning, an afternoon and a night session, with 3 rolls allowed per session (first roll is free, second and third rolls requires watching ads).

Gacha rewards differ by colors:

 * Gold: 1 Ticket or 1 Bell.
 * Silver: 100 coins or 40 coins.
 * Blue: 30 coins or 20 coins or 10 coins.

Times:
 * Morning 12:00 AM to 7:59 AM

Gallery
Where the player accesses character profiles, in-game CGs, and BGMs. You can unlock CGs for free if you complete a chapter in before the early completion bonus ends. Normal CGs require 200 coins to unlock and special chapter CGs require 1000 coins to unlock. You can also unlock character profiles for free by completing a chapter before the early completion bonus ends. If you don't finish the required chapter in the time frames, you can purchase the character profile with 2000 coins each. The entire BGM section can be purchased for 1000 coins.

My Room
My Room is a mini-cleaning game to clean the heroine's room.

After a certain time, rubbish appears. Tap the rubbish to clean the room. If you continue to cleaning, the EXP of the heroine increases. If you level up, the heroine changes her costume.

EXPs are necessary points to continue the main story too. There will be a challenge at certain points.

Get EXPs by regularly cleaning in the room.

You can also use items to speed up your progress. There are bells which invite a colleague over and you can earn 500 EXP. The bells can be gained through daily log-ins and you can also buy them for 300 coins. There will also be a gift box that may appear and after watching an ad, you can earn rubbish for 30(?) seconds to gain EXP.

Trivia
