In my view, the last remaining etiquette. A generation with a proper mindset

It seems like Son Heung-min and Lee Jae-sung are the core line; the rest are politely called Gen M, but they are just a free-spirited generation. That's why they seem to have a lot of complaints, calling Son Heung-min's advice or his commands/actions as a captain "old-fashioned" (kkondae).
To put it bluntly, isn't Son Heung-min perhaps from the last generation that played football even while being hit with bats? That's why his mindset is upright, while the others are practically out of control. Especially Lee Kang-in—honestly, seeing how he mixes informal speech with his seniors, it's obvious. You can't exactly beat him, and because his skill is unrivaled, even if the senior players suggest removing him, it doesn't happen.
