Seeing some dude with a recessed chin act like mewing is fake is actually hilarious. You are literally ruining your face by breathing through your mouth and then wondering why you stay invisible to girls.
You aren't being smart. You are just a hater because you lack the discipline to fix your posture. Guys who actually care about their looks get respect and attention from girls while you stay in your basement with your mouth hanging open like an idiot. Stop making excuses for your weak facial bones and stop pretending looks don't matter.
