Jeongin's sick but doesn't want to worry anyone so he keeps it to himself. It's not until something major happens when his hyungs realise they should've taken action long ago.
Jisung doesn't feel good on a concert. He hides it because he doesn't want the concert to be canceled because of him.
Bangchan still manages to find out and get's Lee Know to take care of Jisung.
