Idk why but everytime I look at Doremy's clothes I get the feeling it would be very fluffy and comfortable to wear. Or to hug.
I mean... everyone wants it to be comfortable while sleeping right.
Honestly though, canon and fanon wise, they make good couple material. Meiko-nee-san is the goofy sake-obsessed one while Megurine-san is the down-to-earth classy one.
