Sure, they’re useful to help me know what sorts of stats people have. 
It’s a stat which defines how Ædmund’s character develops; at this point, I could probably just rename it… 
Alder will not be an RO in the normal sense of the word, no. They won’t be present through the majority of the story in the way that the real ROs are. It’s possible that there may be an ending where an unattached MC could end up with them, but I don’t want to make any promises about endgame stuff… 
I suppose there are reasons why it should be Ædmund. Secret boss ? Plot twist ? Hidden potential ? Or … something even bigger ?
High secret stat makes Eddie into a cute and sexy “bad” boy while if you keep it low he stays a boring goodie two shoes…
See the above post by our dear author for the non-biased explanation. 
But my mc would ideally want Alder in his life, even if he does end up with cute chaos Eddie. Alder is fun whether or not we “romance” him and my mc could dearly use more friends and more fun.
It will be interesting when I kill him ( if our holy author allows it of course )

Chaos Eddie is too cute to kill, as is Alder. 
How did you get all the relationship stats that high?

He disappears down the road, and you head back to helena’s home. Cap Helena’s
he were even attacked by far more Dogs of Karakan. He was?
Do you think he look like a Chosen One? looks
Oh, don’t worry about your friend. she’s not in any danger. Cap She’s
" “Helena, please can I stay with you? I don’t have anywhere else to go.” That weird open quote
That afternoon, you head out to the clothes shop with helena. Cap Helena
For a few more seconds, their uniform switches between the four colours. his?
"I’m not arguing, replies Kevin innocently. Close quote

There’s more at play than just what I know since I have yet to replay, but it’s possible to get everyone’s stats up pretty significantly through the ‘party’ route of the meet 'n greet, ‘get to know yous’ with the study group. That potentially brings everyone’s stats up to somewhere in the lower 60s, with characters like Æddy getting very close to that 70% level if that’s your goal. No idea how anyone can push Charles up into 70+ until I’ve had a chance to (finally!) poke around today.
Nah, I was just joking a bit, but your mc must be really nice to everybody, my mc happens to make a couple of friends more in spite than because of himself.

First time playing through it.
It was pretty good
I keep thinking I made it too easy to get high relationships with people…
