Ok… So I just learned that I actually have a fan club… And apparently there's a lot of members…
And from their explanations from before… The fanclub made a direct plea to the girls that they be allowed to at least have a night to send me off properly before I leave…
Apparently, the girls had believed that because everyone had been holding themselves back from interacting with me, suddenly putting them in the same room as me would not help them either since they were too used to just distancing themselves from me.
So they came up with this plan where Delmare would use her Siren magic to intentionally lower the inhibitions of everyone in the hall which should open them to the idea of interacting with me more.
But well… We know that Delmare ended up overdoing it which was what led to this… And her magic even got to my girls as well which was why Katsuki did what she did.
