ワタシは無実です！
実際は、お湯がさめないようにでっかいスポンジシートのフタがしてあって、そのスキマから頭だけだして入るという面白いスタイルで入浴してました。
ほんとは外しても良かったんですが、またお湯の上に戻すのがめんどくさくてそんなかんじに(笑)

I'm innocent!

In actuality, they had an interesting style of getting in the bath: it's covered with a huge sponge sheet so the hot water doesn't cool off, and you get in so just your heads poke out through openings in it. It really would've been better to remove it, but it felt like it'd be a royal pain in the butt to put it back on top of the hot bath. :-)
