There’s a walkthrough above the credits if that doesn’t help try keeping the meter like this and get his monster points up I’m probably not explaining right

Hi! Yes, that walkthrough is correct, let me add a bit more detail.
Avoid lowering your Determination Points until you go to the kitchen. Help Soren, ask him about the knives, and then choose “Unless you’re going to burn the meat…”
This will raise his Monster points, and your Determination will drop to 5, which unlocks the breakup conversation at the end of the dinner.
Hope this clears things up!
