If i'm aiming for a specific LI, i will use walkthrough on my first run. But sometimes i'm too lazy to refer to walkthrough, especially if I have the love catch on. So i just roll with it and guess the choices. If affection indicator pops up, i know i picked the right one. If it doesn't appear, that means i messed up so i just reload my last save and try again. It is lowkey inconvenient for me to keep grabbing my phone again and again just to check the correct choices when my hands are already occupied with controller :/
