Kids, they grow up so fast. It seems like just yesterday when Francis Ng’s son Feynman graduated from the primary school — it was exactly a year ago when the then-12-year-old looked adorable in his graduation photos. These days, he's looking very different.

Francis posted a photo of Feynman on Weibo on Jun 22, where the 13-year-old was seemingly playing mobile games while sprawled out on the bed. Gone are the chubby cheeks that netizens have come to associate Feynman with. His features have also become a lot more defined in the past year.

As one netizen put it, “We all know that children grow up. But to see that adorable little boy blossom into a young man makes me realise how quickly time has passed.” Uh huh, there's nothing like puberty to remind you that everything's temporary.

Many netizens also expressed surprise at how quickly Feynman has matured. One even quipped that Francis “should watch out, because his son might become an even bigger heartthrob than he is!”

When Feynman realised that his dad had posted this shot of him, he commented on Francis’ post, “What on earth?” Netizens were tickled by this exchange, with one suggesting that the father-and-son pair “agree to only post photos where the other party looks good in”.
