Bossun and Himeko's personalities are still switched on the school ski trip, so imagine the complications when it's time to change clothes or take a bath! And complicating matters is Saaya, who has a crush on Bossun but doesn't know that he's effectively Himeko right now!
...but is it normal to say that 
they're gonna bathe together?!
¿Pero cómo puede decir 
que se bañan juntos?
Mas dá para sair dizendo que
 eles vão tomar banhos juntos?
