At this point, let's take a brief look at Yun's Diary.
"Yun's Diary"
.
Day 0001:
I don't usually write diaries, but I figured if I don't turn my feelings into words, I may explode!
I'm so worried about Ao. The squirrel is becoming weirder every day.
Especially after that particular day when Yona became Ao, & Ao became Yona, and confessed to me & I… well some other things happened too!
But anyway, after that it tried to commit suicide by jumping inside the fire. Gladly I could save Ao, but then the squirrel fell in a depression. Ao doesn't eat enough anymore like it used to, and has lost a lot of weight. Is not that energetic squirrel anymore, & is often spotted just sitting & staring at an unknown point in the space.
I don't know what can I do for Ao, who I admit has somehow become an important & dear being for me. Despite it being an animal, it seemed that we could understand each other like more than just really good friends. I wish I knew how to help.
Maybe I should take Ao to Ik-Su?

Day 0002:
As I pass the nearby lake, I see the back side of an stranger who is standing there watching the lake. And it has the figure of a woman, with long brown hair. Is it an illusion? I rub my eyes & look again.
It's only Ao, standing there. Wait, What?! Where did the woman go? For a moment I have a crazy idea of going near & find out for myself. But for some reason I don't. I wonder if I'm scared.
I turn to go my own way. But then my curiosity wins & I look back one more time, only to see the woman standing there again. Now I'm really scared, & I start to run to the opposite direction. I want to see her face, but I'm afraid of what I may see. That's it! I'm going to visit Ik-Su!

Day 0003:
Ik-Su greets us with a warm welcome, & wide open arms. When I say "Us", I mean Ao & me.
Then for some reason, Ik-Su becomes extra excited about Ao. He says: "What a cute nice being!" Then grabs Ao & runs away!
I don't quite get what's going on here. Did I miss something?!

Ik-su's Diary!

A blissful day:
Yun has brought home a beautiful girl! And it seems that he's quite unaware of it himself.
I can see that it's a wonderful nice lady, shrank into a squirrel's body (Don't know how is that even possible). The poor kid is praying to God restlessly, asking for just a little drop of Yun's attention.
Well, Yun is a really genius boy, so I hope that he'll somehow notice this miracle.
