"“May Umi-chan notice me just a little bit” is what it says, but it’s so tiny you can hardly see it (lol)"

^Oh, is that the artist's comment?

Yes!!! Nagiriku's HonoUmi!! Honoka's little smile at the end and Umi you're such a spazz

yeah from their twitter, as translated by the scanlator

she totally wanted to show some skin to her...lol :p

So is this a surefire method to get Senpai's attention?

I bet Honoka ignored the knocking on purpose. More like she started to pull up her top just to give Umi a peek. XD

She probably thought it was Yukiho and ignored it cause Yukiho's used to her naked arse. But not Umi. So Umi comes in, Honoka panics, she realized she just scored, Umi has wet dreams of Honoka that night, and they all lived happily ever after.
