To complete this particular game, there is a basic strategy related to studying the plot and the comprehensive development of the character and friendly relations with others. If you have problems with relationships: a fortune teller will help.
When players engage in nonsense, pumping up communication points, try to be friends with one character, or do not engage in character development, problems begin in the gameplay.
Therefore, I indicate the optimal path, because after reworking the fortuneteller, counting points lost its meaning.
But you have the right to ignore my answers.
