^lol THIS.
All those info the wotas or antis or whoever dug up were all conjecture. People will believe what they want, that those posts might have been signs of them "dating" and whatnot. What I'm going to say is also conjecture... But I believe those posts coinciding with each other were just Airi being friendly with the foreigner because she's a nice person. She likes happiness and wants to spread her happiness and thankfulness to everyone she meets. That's the kind of person that I see her as.
I believe C-ute's going to rise from this even stronger than ever! And I believe in Airi that she wouldn't get into relationships. She was probably just being friendly and people often mistake friendliness with being flirty. Of course I don't know her personally but she seems to be the type of person who has her priorities straight. She strays, maybe, but she knows what she did wrong and knows how to get back on track. She does her best in everything and is always optimistic and I look up to her for that! She knows what to do in times like this and I think we should all just believe in her! She's an amazing person!
I, for one, will still support her in a positive way despite this because I want to see her rise from this and not get depressed for too long---since she always thinks deeply about things and she's going to think extremely deeply about this. I don't want Airi to change because of this and I'll put my trust in her. Do your best Airi, like you always have!
P.S. Don't take this like it's somewhat biased (it probably is ) because I love Airi so much... but I think C-ute as a whole has their priorities straight ever since 3 of their members graduated. They had a lot of things to think and talk about with each other so I believe in them. They know what they should do as individuals and as a team so I'm sure they'll be fine.
