@@Gunils_Wife Idk why he felt the need to apologize, but you're right, he didn't need to. My guess is he was apologizing for how much he was sneezing and how he had stopped the conversation on the last sneeze with the audible intake of air.
Starting with the one in the white sweater and moving right you have Hwarang. Then it's Hyuk, then Hyeongseob. Then Lew, then Hanbin. Then Eunchan, and lastly maknae Taerae
Lew apologized after his last sneeze and mentioned the pollen, so he at the very least was dealing with allergies. The other were also probably being affected by the pollen to a lesser extent
