In my opinion, most of the national team players dislike Son Heung-min

Even if they don't outright dislike him, they don't seem particularly keen on him.
The trio of Kim Min-jae, Hwang In-beom, and Hwang In-beom [sic] made it quite obvious this time.
The group consisting of Lee Kang-in, Oh Hyeon-gyu, Song Min-gyu, and Seol Young-woo
also seems to dislike him, but they can't show it openly.
Cho Gue-sung and Jo Hyeon-woo just seem to be going along with it.
I'm not sure about Bae Seung-ho and Park Jin-seop.
It's very noticeable if you watch the national team training videos or camp footage.
Son Heung-min seems to be close with Lee Jae-sung and Kim Seung-gyu.
