Yurume is determined to not get out from under the Kotatsu, but after getting it stuck in the hallway her friends try to help remove it. 
So that's why I'm not getting
 out from under the kotatsu!
¡Por eso hoy no me moveré del kotatsu!
¡Por eso he decidido 
no salir hoy del kotatsu!
Então é por isso que 
eu não saio do kotatsu!
