Oh really? So far, the ones with hard proof are Akirose and Azki.
Others doesnt have much weight to it, like how Watame and FBK are married, or that Korone is divorced.
I do know that Choco used to date a guy 10 years older than her in a past twitcast, which I listened to and rechecked after. Kson mentioned her ex bf who introduced her to her beloved Yakuza series in an interview too.
Again, I like researching stuffs(which is why I got the infos about Suisei's mom), and I need more proofs than just the ones on matome/zense sites. and no 2nd hand info like "I saw people said" "Everyone already know that" too
