In all honesty, the entire band, because I love meeting people in general (that and they all seem amazing) but if I have to choose...
Janne because I know nothing of his personality really, and that intrigues me, that and I love his solos.
Alexi, because he seems complicated, as do they all, but because he's the stage man with so many secrets...irresistable to my insatiable curiosity. Especially because you're supposed to be able to tell about a person by the way they write/compose, and I always love digging under those surfaces. That concept basically goes for all the members. haha
