Zuikaku...

...But if Shoukaku-nee is going to protect me

that means that Shoukaku-nee will be gone again and that won't make me happy at all.

I want

I want you to stay with me for your whole life so you won't dare to sink.

for you to yearn after me, Shoukaku-nee.

That's why I think I want you to yearn after me.

I'll show you how much you will love me.
