This is a sequel or an "alternative" version of the previous works?

It’s like the author doesn’t know if they want to cuck the MC or give him a happy ending

So since this is the last one to come out should we take it as a official ending?

@Ronnie42: This was published before the "A" chapter but no one just scanned it until this digital version was put up for sale. Hopefully someone with Japanese skills shows up to let us know how things go but knowing this author it's perfectly plausible the guy in this one just enjoys seeing/listening to her getting fucked by older men, like in A.

Etuzan Jakusui generally tends to have some cheating/cuckolding themes in his works.

@Dynellen so then right order to read would be this?

Jukujoshikousei - /g/1117533/15f0e59f4e/?p=1
Jukujoshikousei I - /g/1155305/1612a885f8/ ( this )
Jukujoshikousei A - /g/1105687/09b1d5a3cb/

@58569
if you go by a realese order - then yes
but Jukujoshikousei A is clearly the sequel for Jukujoshikousei. and this vanilla story is out of place, so alternative version perhaps ?

@ilferion it may just be the author trying to add to the story to make the NTR hit a bit harder.

Ah, yes, good old "draw the head smol to make the whole body look thiccer".

I think it's a if thing like Natsuki -Rewrite- from Kagemusha /g/1042857/474da2f169
Her being a virgin in this doujin should already indicate that it's something else as they aren't in relationship in the Jukujoshikousei. It's like him truly growing a pair in this one and her who doesn't do the dumb thing of going to fuck something else to forget about him. So i indeed believe it's alternative.
Anyway after reading through it i totally can confirm it's both of them accepting each other's feelings. So this is in a way the happy end and the other one the bad end lol
