Using Moresampler the results are very good, but somehow I feel something wrong when rendering. Maybe there is a wrong file setting but I also don't know :(
If you use Moresampler on Boyfriend use rendering option : eoMb-100Mt+30g-3A10 (This is based on the suggestion from HalfneCross). I tried another resampler like a doppeltler him voice became soft.
Sorry, I'm still not good at mixing but the result isn't bad either ^^"
