Nanami almost exposed their relationship! She's so impulsive, but that's what makes her cute. Rin-chan almost saw something, but got distracted by food. Oh well, I understand her. Sukiyaki tastes amazing!
It was smart of her to whisper "I love you" to make Kaoru understand how it feels. He really should have explained first. Now they can play the "I love you" game to see who can get the most flustered by "I love you" at random times!
Kaoru is all attack, no defence. Well, like most characters in romcoms, really. Definitely including Nanami, although she's not that strong on attack either. Or maybe strong but unreliable?
