The first kidnapping victim is, as far as I remember and know, still in charge of the track club members.
The childhood friend is, well, being kept away from the MC like always, at first I believe it was due to the meddling of the Succubus, but it that was the case, I am pretty sure he found out about it recently and, if so, now I don't know why he would be purposely staying away from her.
Man, I feel like I need to make a document to keep track of everything, but I can't be asked to with this many chapters.
