Is there any walkthrough of this game??
Look for characters with a green name. Green means that the story can evolve.
Yellow names mean that you need to unlock another event first (or earn relationship points).
If there is no name in green or yellow, "advance time". The first week (within the game), has little event. You will advance time several times.
Save the game when you use a pill, because in the beginning you can run out of memory health (game over) if you don't recover your "memory healthy" in some scenes. And avoid using 2 pills in women's food/drink in the same week until you understand the mechanics of the game.
At some point, you have to discover the "weaknesses" of the characters. Is not difficult. If you make a mistake, try again a few days later.
If you get stuck in the story at some point, go to the map -> shopping and see if you have anything to buy. Or proceed to the next therapy session.
