What do you think? Which one do you like most and why?

Raizel x Lord

Shinwoo x Seira

Rael x Seira

Yuna x M-21

Me first:

rai x lord (totally disagree - why? I don't know.. I just don't like her)
shinwoo x seira (its nice too but hints are so random)
rael x seira (she didn't like him, but hes more likeable these days compared to his first appearance)
yuna x m-21 (its almost non-existent, easily missed)
