Identify searching for a game

[Loolie2000]

Hi folks,

im searching for a game with the following:
it was a rpgm game with 2 sisters and a mother
one is younger and timide the other older

the only areas there are is home, a train and a school.

on the train the sister can get groped or sit on your lap
the sister is also a redhead.
you could help her study and unlock new scenes like that

as i remember correctly too,

there was a scene in the school where there are 2 guys bullying a girl and you could intervene by catching a backpack.
