The interview boycott was the final blow

The rift already existed even before the player was disparaged by a reporter's comments regarding military service, but the interview boycott seems to have been the final blow.
Since they already disliked the situation, there was no reason to support a collective interview boycott, and it seems the '96-line players exploded when there was pressure to boycott all interviews.
From Hwang In-beom's perspective, having scored a goal and provided an assist in the World Cup qualifying match and being named MOM against the Czech Republic, he would have wanted to show it off proudly to his acquaintances and family. It is somewhat natural that he felt angry and hurt when Son Heung-min told him not to do interviews.
However, while Son Heung-min emphasized a "one team" mindset by calling for a total interview boycott, why did he take a separate flight back to Korea?
Eight players, including Jo Hyeon-woo, Lee Kang-in, Oh Hyeon-gyu, and the three '96-line players, returned together with Hong Myung-bo, at least standing by him when he was being criticized. Doesn't it look strange that he returned quietly on a separate flight while being cheered?
