I'm the same! I feel the cold a lot, but I also start to sweat and become uncomfortable at warm temperatures other people are enjoying. I'm somewhere between 5'5" and 5'6" and 120 lb (so Nissy's ambition is to weigh as much as me. >.> )

Misako never stops being beautiful, but I'd be very, very happy if she'd gain just a little weight. :/ Shin could also definitely stand to gain some, and I'm sure both Mitsu and Shuta have lost in the last year or so.
