Maybe Kirei's looking out for Sakura and sees the MC's true intentions as nothing more than surface-level satiation? Maybe she feels an intrinsic need to keep Sakura 'safe' due to Sakura doing the same for her after Kirei's own tribulations? Or maybe she's simply jealous of Sakura getting closer to the MC? Lots of ways to read into it
Yeah I would have made things ten times worse if I were to handle that situation.
I know she has her reasons, though I do wish Arvin wasn't just trying to make excuses but that's where he is at emotionally I suppose. I can see how it could come off as him taking advantage of Sakura's vulnerability. I'm not saying Arvin calling her out or snapping at her would have been good, just cathartic I guess. Maybe a way of failing her route if you as a player chose to have him flip out at her and/or lose patience with her.
It was more about just having a bad option I guess. A way to just be like "fuck this" and walk off, getting a bad end lol.
But like I said, I am curious to see where her story goes. I haven't got that much further but it was nice that
Yuna was the one to talk some sense into her, means the characters aren't completely reliant on MC to solve all their problems.
