Oh my god that's a combo. A 'group makes noise and gets caught' situation can be great and even funny if they're somewhere safe or unaware they're being followed, but having them suddenly forget what they were doing to talk Because Plot is unbearable.
Two characters in a love triangle randomly fighting over the third in general is also rarely done well and sometimes feel outright gross. I might be sick of it because my country is way into soap opera and it's always on TV somewhere, but the third person should not be turned into a trophy or just stare at two characters they supposedly love acting childish(unless it's part of their character that they have a very short fuse, but sometimes it's hard to believe). I actually really like the ending of Super Mario Odyssey for subverting the cliche, even though the plot is a footnote there.
