It seems like Son Heung-min practices social distancing

Back when Hwang Hee-chan appeared on You Quiz during his Wolverhampton days,
when they asked what he does on his days off and if he meets Son Heung-min,
he said if he has more than two days off, he goes to London,
but whenever he calls Heung-min hyung, he's always busy with plans,
so he just hangs out by himself. He even said he hadn't seen him once in three years in the UK.
Even considering it's a variety show, if they had met even once a year,
he would have said he couldn't see Heung-min hyung often because he's busy.
If they had met even once, he wouldn't have said he hadn't seen him at all.
It seems like his style is to only hang out with people he clicks with and is close to,
while telling everyone else, "I'm busy, let's meet next time."
