I mean there wasn't anything important on the school route either in terms of sex scene except a NTR groping scene with the childhood friend and a new possible LI introduced who probably is already raped and severely injured.
Some context to the missing persons in town was given, tho, so we at least know where the group will head next.
That scene were your group is captured and the girl in the safe happens on both routes, it's were both path merge, thought with some differences.
Also calling it a
ntr scene is a bit off, yeah they try to rape her, but the MC kills them before anything can happen, the injured girl...yeah, very likely a rape victim, if she survives who knows, personaly i hope not.
The going home route has some more context about what happened in the city and people, the talk with the soldier.
The school route has some more info about the meteor which made the sun explode...i mean, it's a ridiculous explanation, done by a high schooler... but whatever. Also school route has content with the teacher and a other classmate, personaly i find this path better so far.
