We’ve discussed his kissing policy why Sukkie kisses on his hand, not his eel’s hand a lot here. And it became a bit of news this time in Japan. I think there are various reasons for him and for his eels he kisses. But I think we keep it his secret.
IF he held my hand like this so gently, I would die for happiness… *beyond faint*
