What chapter was the shower kiss?

Chapter 4.5, it's literally named "KISS".

Yamashiro will be at the epicenter of the climax

So we might get some insight on her past with Yatsude...

And then BOOOOOM! They exploded from the massive gayness that built up inside them with no release.
Like, Tsukushi seems barely aware of how thirsty she's behaving...

"So in other words, they're best friends!"

Mizushima, dude...

Short.

Maybe you'd be better off without the prince as well, huh.

And they were best friends

Starry skies make you gay, huh... The more you know.

This feels so much like the early chapters... So much soul-healing, thank you.

That "haha" is sooo painful

As Wanko would say it... SAKUMA LOVE

Alright, we got the Subtext tag. Let's hope next amendment to the tags is for Yuri.

Oh dear, this is becoming gayer by the moment.

"Plus they're the perfect size to be hugged!"
"I dunno they're a lot bigger than you, Shima."

Could be implying body pillow is too big for Shima, could be implying Shima is the perfect size to be hugged...

It's funny because the body pillows the two of them chose for themselves both look like each other (the cat looks like Ise, and the rabbit, like Shima). Obliviousness wins the day, I guess...

The author really seems to be setting things up for them to end up together...

The Polish-Lithuanian Commonwealth of yuri then :)

Le oof.

...also pretty sure that'd end in NTR or something D:

How about Castile and Aragon kingdoms into Spain? They've yet to split up
