DON'T SLEEP ON THIS MOVIE! This would've been a great series but I think a movie fits it perfectly. I loved every second of it. Something about boys with braces is so damn precious and Earth's smiles are to die for! The fluffy romance will leave you giggly and full of smiles. I didn't have constant anxiety and it wasn't cliché or tacky AT ALL. The plot/story wasn't too basic which is always nice. I'll definitely recommend to a newbie BL fan and my re-watch value is high for good reason.
Enjoy....
