It’s called “happiness” hun..he smiles so much now cause he’s actually TRULY happy..when you’re truly happy, no one and nothing can ever stop that…sometimes you even catch yourself smiling to yourself and you don’t even know, cause you’re just dazing off thinking of the one thing or person that makes you happy the most so you can’t help but smile. I wouldn’t say he looks like a bitch, I love guys with “natural” smiles..it’s way cuter than a half ass forced smile.I would just say he finally has a reason to show a real smile :D ^____^ :) <—look at all my “soft” smiles..enjoy!
