This happened when they met for the interview with VOICE BRODY. The interview itself went like this:
Aiba: Everyone calls you ‘Ayaneru’, right? How should I call you…?
Sakura: Anything is fine! …Perhaps something like ‘Ayane’.
Aiba: Will it seem like I’m being too arrogant? (laughs)
Sakura: No I’m sure it won’t!
Aiba: Then I’ll take this opportunity to ask if you can call me ‘Aiai’?
Sakura: Is that okay?
Aiba: You’re the senpai here so it’s totally fine.
Sakura: …Okay then. (awkward) I’ll call you Aiai.
Aiai: Fufufu, I’ll call you Ayane!
