On your path as a legal demon slayer, you eventually had to go to the butterfly mansion to heal your wounds or be helped by a Kakushi, that same thing happened, and you met Goto.

Anice coincidence? Maybe, but you appreciate it.

Eventually and somehow, you became close to him, you even started dating. Nothing could go wrong in a world full of demons and constant danger!

Maybe it was a nice way to distract yourself.
