Laying down on the couch he puts his hands behind his head, thinking for a bit. Sitting up he looks at Yuki, "Can't you go further up the mountain where its colder? Or maybe a cave up that high? I know caves tend to get cold, but I haven't been on this mountain for long to know how cold the peak will get. But I have the feeling that would probably be your best bet if you don't want to melt. But if you've never experienced this kind of heat before that you can remember, I would think you hadn't been here for long. Or at least not this mountain or else you would probably remember feeling things getting warm because of the change in the seasons."

Yemon wonders why she doesn't remember the weather getting warmer, from his impressions she's been around for a while. But with her not having been through the weather getting warmer maybe she's been here less than a year and just doesn't remember?
