>>84088725ERB doesn't really interact much with other members to the point that she doesn't really have a specific member to be paired up with specifically. At least with Ina even though doesn't have a single member she tends to get paired up with she's still included in various groups due to how friendly she is with everyone. ERB is just weirdly isolated and is only brought up when she does a voice imitation or when Nerissa is involved which is basically just pre-debut lore RP (doesn't help either that ShioRaven is a juggernaut of a pairing after BD).
