That grilled meat analogy that Gotou used(And I could be over analysing this due to booze..) seems like, She wasn't interested in MC until she thought he had found himself someone else. Thus the whole "well done" shit. The rest was just a way to justify her rejecting him. When she thought he had found someone else, She was interested. And BAM! "I wanna meet her", To make sure he's not lying?
