Stuck in 428's Suzune's Story! (spoilers)

[Joueur Citoyen]

Hi people at Fwanovel! I've been reading the boards for a long time but I just registered.

I'm sorry for asking for help but I'm stuck in 428.

SPOILERS AHEAD!

I've played Suzune's side story but I can't jump from Suzune to Achi.

Do you have a clue to why?

Thanks for your help. 

It's my best game ever!

You have to reach the true end first afaik. Also you just unlock some bonus content by jumping, it's not necessary for completing the story. In case you get stuck there's a walkthrough in this forum.

Hi, thanks for your reply. Well, I did play through both endings (SPOILERS : when Osawa dies and when he doesn't). I also played through the Suzune's and Canaan's story. I could jump from Cannan to Maria and back to Canaan without any problem but not from Suzune to Achi. Maybe I've got a choice I should change somewhere on the time chart, but I don't know where.

I've sent an e-mail to Spike Chunsoft, maybe they'll answer. I'll update the post when I've unlocked it. :-(
