These brief guides will just briefly explain how to get the different endings of the game. Meaning it won't contain any spoilers for the following endings:
Also, all of these ending require you to go through a search, which there is a brief guide located here:

(3) Don't work overtime.
Seventh day: Nothing to do here.
Eighth day: See the search.
NOTE: There is no set rigid rule as to the method for getting this particular ending. What you see below is just one of the ways to get it. This ending is the most common and easiest to get, and can be obtained by randomly going through the game.
1. When pouring tea every morning, it doesn't matter if you let the blinking light run out. Don't pour to one particular person every single day; vary it.
2. For the first two days, don't work overtime.
3. From the day where Ed's sick, start working overtime.
4. On the search for Ed, let Al stay at home for the first two times.
5. See the search
At some point in the game, Al and Roy need to find 3 clues in order to go into the Fuhrer's office. Both of them will get their turn to go on a search:
Al on the search:
(1) Firstly, go to the entrance of the military headquarters and talk to the guard.
(2) In the marketplace, 2 boys will run into Al and one of them hurts his leg. Choose the option to take the kid home, and Al will hear something about a strange man in tight black clothing holding a beautiful shiny watch. [NOTE: If you don't get this on the first attempt, go back to the marketplace again.]
Roy on the search: (1) Go to the Fuhrer's office and find it locked;
(2) Go to the break room and 2 soldiers will be talking nonsense. Pick the option to continue hearing their conversation, and there's the clue. [see screenshot below]
(3) Go back to the break room again, and the 2 soldiers will continue to talk nonsense. Click on the option to continue hearing the conversation, and there's the last clue. [NOTE: If you don't get this clue, then try going elsewhere first, and then coming back here. That should do the trick.]
When Roy does the search, do not go to the entrance of the military headquarters. Otherwise you'll get a game over.
