There's A, B and C split on Day 26.
A: Picked "Keep pushing" and convinced Shoichi to meet his mom (depends on the choices made during Day 22, 24 and 26).
B: Picked "Let it go".
C: Picked "Keep pushing", but failed to convince Sho to meet his mom.
Later on on Route A (Day 30) and B (Day 29) there will be a choice in conversation with Saya that will have an impact those routes and cause another split on Day 38(A)/37(B):
1) Bad: Route B + "College advice" during Day 29.
2) Best: Route A/B + "Relationship advice". Or Good: Any other combination.
