you saved her from yhwach a while ago and brought her back to hueco mundo to help her back to her feet and after some time she got her rank back in the espadas and over that time she has developed feelings for you

Tier Harribel: you were walking around hueco mundo and you feel someone rubbing your hand and you look and see her hey there my darling~ she blushed lightly and leaned her head down to yours do you want to go home and cuddle <3 softly smiles at you
