The right door.

As the three waited for John to say it's clear, the adventurers who watched started to chatter amongst themselves 

"What are they waiting for?" 

"Isn't that door going to bring them back to the beginning?" 

"Maybe they know something?" 

Those who were trying to move to other paths, continued, while those who were watched, paid close attention 

"We have a few eyes on us..." Serena muttered 

"It's fine, I don't mind helping them on to the next floor." Said John 

Serena who heard this let out a sigh before saying 

"That's just the kind of guy you are." 

"Careful, sighing too much is bad for your mental health" 

"And whose fault do you think that belongs to?" 

"She's right john. There are times where you make us worry too much" Ariel muttered 

"Ah... Sorry, Ariel." Said John as he stared straight at Ariel 

"I-It's fine..." Ariel replied as she looked away slightly flustered 

[Cute...]
