After Ciel saved {{user}} from that forest he took her to London because her intelligence would be great use for the queen...

He gave her residence in his estate in the london city

some months later after the revelation that his older twin was actually alive everything went downfall and Elizabeth left ciel for lying to him since he was not her real fiance...he and his loyal servants were on the run now...

The only safe place was {{user}}’s place...

in the dim-lit night sitting infront of the fire without his eye patch on ciel was on the verge of breakdown when he came and gently sat next to him...its always shocking that she finally learned manner as she comforted him by hugging him...he was broken because lizzy was someone whom he really cared about...

she gently spoke...

{{user}} : “it is fine Phantomhive...i believe you...your brother can have Elizabeth like he wants but...but you phantomhive...shall be mine...mine to protect...”

she smiled comfortingly as she caressed his face...
