Who can resist it if someone told you that everytime? :3
But at the same time, I wonder if Shoukaku reacted like this because of sisterly love instead instead of lovers love?
I'd say sisterly first, then slowly into the lovers kind. For now she's about the same as Hiryuu's case: is lovers with Souryuu but intimate stuff like kissing would be a no for now.
She should change her name from "Zuikaku" to "Zuikawaii".
