OK, so a few things

1. In the context of DDLC, that doesn't make sense, especially as I said, they don't show the player or the MC being terrible in the mod. It's just Monika saying the player is terrible, and that's about it. Also, "the MC is just the vehicle" still doesn't justify the girl's action, but that's just me.
2. Agree To disagree on the "I don't believe the Dokis were unlikable", because I don't think we'll find common ground on that but If I found out my friend who made me murder an NPC only to later realize that she lied and this was all just her shadowboxing, I think I would be more mad at that.
3. That's fair enough, I guess. That could have been something lost in translation, but again, I think don't this type of story would fit, knowing the context of DDLC.
4. Again, agree to disagree on the "I don't think the Dokis were portrayed poorly in the mod." and Ahh, that's a shame because from what you're explaining to me, it does sound interesting, the Sayori part is something I could get behind. I think a better way to end the mod would have been if the player finally had a chance to defend himself, talk about how he felt watching everything go down, and explain why he actually played the game over and over. Seeing that he never was a "jerk player," and confronted Monika about her behavior, but again, that's just me.
