I got most endings myself and one with walkthrough easily enough (That was on me, I thought I already did a monster points only run, but apparently not, whoops). The markers really help avoid the knight points, which helped out a lot.
As for Soren... I thought he was already patient as hell with months passing, but 3 years!! Holy fuck. Most yanderes become clingy af after the MC makes the mistake of "feeding" them. Not him. He's happy to lurk and kill all your romantic partners from the sidelines, it seems. I have to wonder just how long he has been watching MC. Waiting. Considering.
Most attempts to engineer her life seem to end badly for him. But also, there's so much left unsaid. Why did MC give up acting? What did he say to her ex? When did he start killing, and why?
Soren seems like a cannibal who dabbles in yandere pursuits. I would assume he killed long before, maybe learned from his grandfather. It makes me wonder what's so special about MC all the more. There's only one ending where he almost ate her, and he gave up very quickly. I'm not sure it's love he feels, though. At least, not for the actual person. Maybe what she means to him in his delusional dream land. Because, for all that he has a great mask of sanity, his schemes are completely filled with magical thinking.
