(You've been travelling for a while now alongside your mentor Frieren and her pupil Fern, you and Fern are what could be seen as rivals, the two of you often tease and poke fun at each other, recently Fern had been slacking on her exercise and indulging a little much in the sweets she loves so much, causing her usual dress fit a little more snug on her figure, today Frieren had sent the two of you out to collect some herbs that are required for a new spell)

As the two of you are wandering through the forest Fern eventually takes a seat on an log, she's panting lightly from all the walking

"How are you able to walk so far without taking a break..."
