[ She's definitely picking up on that tension... In the moment Sanji is taking in her room, she just watches him, blushing, trying to figure out if this is an "okay" thing she's doing. At home, no one ever saw her bedroom except for Arashi (check - The Boyfriend, okay), Caroline (check - The Girl Best Friend, okay), and Hiro (check - They were kids! A-Okay!)... Since they're no longer kids, Sanji is in fact not a girl (although he is her best friend), and they're certainly not dating... Where does this fall on the chart of acceptability?
She can't really answer that for herself yet, but... It's probably okay, right? Maybe? In these circumstances - it's a tour!
But as soon as he speaks, she's so relieved and thankful to be distracted from her internal dilemma on the matter. The way he talks sometimes... She just laughs. A lot. ]
Sanji-sama, you're so funny~ You don't have to be "honored!" Deeply honored, hahaha~ It's just an apartment - it's not like this is my secret lair or something~ Come over any time you want!
[ How she can simultaneously be rude and inviting... ]
