Does this mean lots of blushing and stuttering etc.?

Uhh, kind of?

I don't think shy and bold were maybe the right way to describe what I'm aiming for tbh.

It's more like the difference between soft and challenging?

Like, yes, on the shy choices there is some cutesy fumbling, but I'm not all that good at sweet lol, so there won't be a lot of it, not in any extreme measures anyway, and any real shyness will have worn off by the hard crushing stage.

The main differences I've noticed while writing is that the shy/soft options take most of the flirty interactions to heart, like they're very genuine, and they have more external physical tells, blushing, skin prickling, sensitivity, goosebumps etc.

Whereas the bold/challenging options tend to be more playful and light hearted, a little more confident, and has more internal reactions, having wandering eyes and getting distracted by the ROs physically for example, as well as warming, aching and all those other neat urges lol.
