>>25167958That part when Reimu calls him during the ASMR obviously was scripted, Vox shuts her down quickly and turns back into the audience, saying that talking to his friend (Reimu) is less important than having a good time with the audience right now.
I thought it was a smart idea from their part, because Vox and Reimu's proximity make some Kindred fans upset, so having a moment when he explicitly shuts her down in a stream would be way to circumvent that. But guess you can't win with rabid fans anyway
