I prefer the mixed cast of main characters who would rotate from time to time depending on who the focus would be directed.
Since I started reading this story seeing a banner about a nymphomaniac jester girl, and a female knight, not a kinda thief boy story, so in a way first chapters were a bit of surprise for me how much focus was given on Crest and his backstory.
I'm actually like that Crest stopped being the "main" character, we get the basics about the story from his perspective as readers, get to know May and Bern from a stranger look, when we learned the thing we had to to grasp the circumstances correctly regarding Bern and May relation, the focus was changed accordingly so we could start the real story.
I'm too one of the few who finds Bern and May relation a bit forced, but what can you do, that's love
On Bern place I would dump May 100 times already, someone says that Bern being her usual self is all the time all the same in her thinking and actions, for me that's actually a big plus, that she's doing in what she belives is right and try to stick to it.
But I too enjoy this time when Bern is not with May(and where May is not in direct danger so all thoughts of Bern wouldn't be focused on her), like other I think she needs her own alone time to shine a bit, spread her wings.
The same with Crest, to get of the May 'hook' for a while and get his own adventure.
Since chapter 31 title is Anticlimax no wonder it's Crest chapter, since I find his character a bit dull from time to time, like you get in stories a usual boy character into who majority of male readers could easily self-insert, sorry I can't do that with Crest too much
