Ahhhh i see! I get it!
Lelei knew Itami spent the first night with her in special region back then, and she doesn't tell anyone.
And this is the second night Lelei sleep with Itami but she's more clingy to him now.
and the third is at the Hakone.
3 Nights Ceremony heh.. She's already have a plan ahead before Rory and Tuka.
Damn u Lelei smart as hell 😂
