MisterZone You might have guessed it right, bro.
FNBE means ''Fanbox Exclusive''. My guess is about some sex scenes of Saeko x Fuku (bestiality). It's just my guess.
My Theory:
Seems like we might be getting Saeko's POV during Seasons of Loss: Winter

It clearly says "SOL Board (Spring)" on the upper left.
Yet, there will be "3" Alt/Alternative Chapters that will take place during Winter.
My guess is that will be Saeko's POV documenting her trip with Fuku during Winter/Christmas Eve.
Alt/Alternative = Non-Canon
Which surprisingly coincided with the Non-Canon (Romance Choice) in SOL: Winter
If you choose to go for that Romantic/Non-Canon/Alternative Route with Tsugumi, you will get this dialogue:
"3" Alt/Alternative or Non-Canon Chapters documenting Saeko's entire week trip with Fuku during Winter/Christmas Eve.

I know there's a dialogue pertaining to Saeko and Fuku in the Canon Choice as well:
Saeko on the Canon Route wanted Tsugumi to join her and Fuku during Christmas Eve/Winter.
No alone time between Saeko and Fuku in this Route.
Most likely proving that Canon Saeko and Fuku's relationship is purely non-sexual.
Now, this dialogue is also Canon but, this is after Tsugumi have been corrupted by Mr. Yamada. Saeko and Tsugumi's relationship has soured badly:
Saeko most likely left with Fuku because, she can't stand cigarette smoke and it's bad for the dog to inhale that.
Tsugumi now hates and is in a fight with her Sister Saeko try to make it seem like there is a forbidden relationship between Saeko and Fuku(which is false),
just to ruin Saeko's image to Satoshi as seen here.
"But, then again these are all just fun speculation while waiting for that coveted release date."
