How to get Step sis H-Scene?
There's new man. Noriko's Femdom Route, Asami's Befriend Route, and you can refuse Sakuya's initiation. But yeah it's laggy and buggy but it's because they switch from Ren'Py to Godot they said that in the announcement.
Go to the bar in the morning so you can increase your charisma
I think Noriko's femdom route is still in development so if you want to expand Noriko's route is by choosing Maledom or Blackmail
Probably do the girls event
