"Everything starting point has 3 main choices and every choice has 3 branches." -Sparkker (Bored)
Meaning:
Your choice can either be a positive, negative and a to-be decided choice. If you imagine Kagari's life theory, the two branches going to the side are the positive and negative, while the middle one is the to-be decided one. A to-be decided choice always align to a positive, negative or neutral. If it doesn't, then your story will never end. Although, it doesn't necessarily mean that the 3rd choice is always there. The 3rd choice is the neutral chain bringer that brings the possibility of going a new kind of positive.
