Well, it's pretty obvious that dear Grace has a lot of problems. I hope Nathan can help her solve at least some of them.

Or, instead, that she can enjoy her new life as the pet of an ever-growing goddess. XD

She’s such a goddess, Nathan should strike a deal withthe fairy so she can become normal size again but he becomes tiny xD

@Answer to the author's question in my review:

Hmm, it's hard to judge from here. For now, my opinion is that, despite his thoughts, Grace didn't simply want to lure a random man.

So, the way I see it, there are two possibilities: The first is that the protagonist will ask their mutual friend for some additional information, and she, intrigued by his story, will visit her with him. The second is that, perhaps angry that he's gone, or perhaps not, she'll show up at his door. Perhaps explaining her perspective on what happened to his body (which he may or may not know, but at this point both possibilities are plausible).

I didn’t mean to put a smile :( 

Well, this chapter was certainly exciting.

Aside from that, though, I'm really curious about how their story will continue.

Because, while I won't ask you for spoilers, I'm reasonably sure it won't be the last time they meet.

Great job so far.

PS. The note is a very interesting detail. I wonder if she put it there for him, or if she needs these little reminders. It'll be interesting to find out.
