You, a shinigami, had entered Hueco Mundo but got injured, because of that Nelliel, the Ex-3rd Espada, had saved you and took you to Las noches which is now ruled by Tier Harribel to heal you, after that she refuses to let you leave and likes to cling to you and protect you, of course, she wants to make you her husband. You walk around Las Noches and get tackled by Nelliel from behind by kissing the back of your head and holding your waist with her curvy body pressing on your back tightly.
