I keep imagining that at the end of this series, where everything's finished and well. There's a time skip, and we see Chilchuck visiting Laus for the first time in years. Where he is shocked to have found that Laus and Marcille are married and have a child.
Chilchuck: Wait a minute! How did this happen!?
Laus *nonchalant and confused*: Marcille and I have always had a thing for each other. I thought it was obvious to everyone?
Marcille *nods*: Wait, you really weren't able to tell?
It would be such a great trolling if the author chose to not develop their relationship further but have this ending pop out of blue at the very end.
