It would be funny if it was over Suzu joking with Mei but it appears to be an angle.
Here's a link to the IG video:
https://gofile.io/d/hsprZ3Short summary is Mei asks if Suzu's drunk, Suzu says lot of people think I'm drunk because I drink a lot but I'm fine. They talk about not wanting to create this type of atmosphere between them.
Mei tells Suzu if something is bothering you tell me. Suzu says people are listening, can you not ask me about this on Instagram? Then suzu goes into a promo about losing to Maika (calls her a lesbian) and then the tag match.
Suzu says it's not too often you get chances like this. Then says she's sorry she's talking like this.
Mei asks why she's sorry and says she doesn't understand Suzu and why she's talking so fast.
Suzu says she feels like it was a blown opportunity. She wants the red and if they can't win the tag titles how will she ever get a rd shot again. Suzu says she has to stop talking about the red because she's gonna start to cry.
Mei acts confused like what are you talking about and then Suzu says I don't think anything good will happen if I talk anymore so I'll just leave. Then it just ends.
