I assume it's just that Bizel doesn't want to deal with the anxiety of being in proximity to half a dozen dragons.
Looks like Fuushu feels the same way later in the chapter, retreating rather than getting involved with a dragon banquet.
yeah it was something that happen on repeat in the novel with how many time MC attempt to put Village's guest at same VIP table and all of them that wasn't ancestor or dragon just shit themselves(with demon king always be the victim).
manga did remove some of those bit thou. like the chapter where hikaru just return from hot spring search trip and Doriam is just weirdly happy to see VC. Is explain in novel
i am going to summarize it cause i really love that chapter.
MC/VC gone from village and left Alfred to be temporary leader, this of cause, motivate everyone to work harder cause they didn't want to have trouble during Alfred rule and depress the kid.
The problem is that Doriam just happen to visit village chief during his absence and nobody told him
to make it more funnier is that, as we all know, the trip just happen to include everyone that can talk to dragon.
So every resident that left in the village just doesn't know what to do with him and just give him food silently while Doriam also just doesn't know what happening cause no one tell him anything.
so we have
-village resident that afraid of offend the dragon. and cause trouble to alfred.
and
-dragon that afraid of cause trouble to village chief's people.
it just left everyone tense all the time till VC come back.
but this part wasn't in a manga as far as i am aware.
