Look. that's the inn where we're staying.

Zentai teki ni sensation - music video
First impressions are everything
A loli sister-in-law isn't all that bad
I can feel the romcom waves
She's just a pervert
This woman has given birth?
I know! i'll fill it with a sister-in-law
That is that, and this is this
Only a sister can heal a scar left by a sister
How humiliating, i'm so embarrassed!
Looking up the term ''lovey-dovey phase''
Enjoying the handkerchief
Do you get it? i get it.
