I see.. I didn't know Fuuko-chan had one too. [ Apparently it's not disapproval. It's difficult to tell with Kotomi since half of the time it's hard to say if she's feeling anything from the way she acts.. but she's nodding a little, that's approval, right?! ]

That means you'll make each other happy, right? I thought that's what boyfriends and girlfriends do. They give each other a really, really warm feeling inside..
