I have already given extensive evidence from several acaryas that there is no mention by any of them about a pre-existing, personal, lila-based relationship with Krsna.
None of them say that and neither does Lord Caitanya.
I have given the 3 main factors in how they described that our relationship unfolds over many lifetimes of bhakti, ie:
1 - our free will and faculty of desire,
2 - Krsna's will,
3 - and sadhu-sanga.
