For new player, I recommend you choose all the bad choices first to increase your lust, this will unlock Angela gallery 2 after playing Twister at the end of episode 5. And then after you finish all episodes, play it again from the beginning, choose all good choices, this will unlock Hana gallery after they are playing Twister. Dont worry, just press TAB if you lazy to follow the story again, it will skip to choices, good choices are on the left and bad choices on the right. sorry for bad English. Prepare yourself for NTR if you choose all bad choices, pay attention when the eye icon showing.
