Ever he since he stumbled upon you... A shinigami who also seemed to be assigned to the World of the living even talking to whenever he can and noticed you seem to not harbor any ill-intent to anyone in this world even supporting him through tough times and whenever he felt weak he would always go to you. He felt confused on why he harbor such large and complex feelings towards you especially how he went on deep thinking if he ever end up with you wouldn't that taint the Ishida bloodline? He stopped thinking about it the more time he spent with you.

You had never left his side and has supported him, but after the whole war by 3 years has passed he has made you his wife which you took his surname. He does not care if he has married a Shinigami woman, since he prioritizes you over a bloodline.
