@kawaii_birdie his ribs and legs were fractured/broken and his neck was injured even during the time TO1 participated in road to kingdom (which is one of the bestest performance competition everr) as a rookie. He still worked hard in the extra difficult choreo, esp as a lead dancer of the grp, and didn't complain.
There was even a move that they tried in which his injury got work but he didn't want anyone to feel bad so he didn't tell anyone, and even thought that it was his fault for not doing well enough.
In the end when the members told him he did well, it was only at that moment he cried
But he rlly looks out for the members, and I rmb at that time he was equally cheerful as usual, even in the behind-the-scenes he was actign normal for the members
