I tagged the bubbles, but not confident enough in upper left to tag it. It's 男装してるのに気付かない百合イカ. Which I think is something like 'Even though disguised as a guy, it's still secret (unknowing) yuri isn't it?'
Eh...?!Yuri squids not caring that they're dressed in male clothes.Um...I am...
a GIRL...*blu~sh*
