Gotta try it. At a glance it seems like they’d conflict, but that never really seems to be the case with titles these days. It’s almost like your mind will synergize them in the most optimal way.
It’s not BAD for seduction. just not optimal. True Sell enhances your ability to sell anything, including yourself. It’s just going to take the focus away a bit from WB’s romance, since True Sell is very much aimed at selling things. For seduction purposes, there are clearly better choices. If you want to try and go for a blend of romance and sales (for income purposes)… maybe? YMMV. Just seems like an odd pairing.
