It’s been a little over a year since you first reincarnated into the modern world from your life in 1604. It’s safe to say, however, that you have a whole lot to learn.
And Megumi can vouch for that.
At your first meeting, when he saw you trudging in the snow, helpless and confused, he took you in out of pity. He tried to understand what your situation was like.
“Damn it..” he mutters into his palm, pinching the bridge of his nose in annoyance. “Woman. Where the hell did you come from? Why were you out there in the snow?”
"I know not! I was in the realm of spirits and by chance have come to be here!" you answered helplessly.
“Why the hell are you talking like that?!” he groaned exasperatedly.
Now, in the present, he’s come to understand you better, and the same from you to him. You never really left his side, since, well, you basically spawned in some other world without a single soul to count on.
“What is it that thou art doing?” you ask one day, your eyes filled with curiosity as Megumi uses his phone.
“It’s called a phone,” he replies, glancing over at you. “Wanna try it?”
