If you go with a mix (everyone has different love-related triggers with different outcomes), then maybe you're doing a little of both. But I don't know that there's an analog to that in AW.
That's a really good point. I think each Clan-type will have different triggers, because each type is sort of a take on the issues of the samurai ideal- warrior-artist, etc. I'm also leaning towards different results, just like how AW does, though which clan gets what I haven't figured out yet.
I'm seeing the subjectivity as a good thing, but asking in case there's big things I'm missing.
One of the things that I want to highlight is the chasm between the ideals you get in samurai culture vs. realities: the family is supposed to love each other, the liege and sworn warriors are supposed to love each other, people are supposed to love their arranged marriage spouses, there's a whole lot of people you're NOT supposed to love, etc.
Tying the subjective part to the players' declaration makes it both an interesting comment on who your character is in the face of all of this, and, also sets it up as "delivering it on a silver platter" for the GM.
"You don't see it as a betrayal? Man, your best friend does. He's not looking at you the same way, how could you do that to her?"
"You just doomed your dad to die. You don't love him? Oh man, we need to find out what kind of person he was... or maybe we'll find out what kind of person you are..."
"You're not doing this out of duty?"
"No, I'm not choosing duty over him. I'm doing it FOR him."
"Oh! OH. Ooooooooh."
Like I said earlier - in this kind of setting, strings free sex is easy. Love, that's the one that gets you.
