Nah, I'm sure its another teaser. The whole comic is full of nascent relationships that have the readers perched on the edges of their seats as they read, only to end up waiting impatiently for the next installment.
My feeling is that at the moment a manga’s male and female leads say ‘I love you,’ it’s like their story comes to an end. So because of that, it’s important for them to not express that feeling in words.
I always found that annoying. It meant that stories had to stay in "Will They Or Won't They" limbo no matter how long it ran. Because, you know, there couldn't POSSIBLY be any kind of character friction in a relationship, once people start going out, it's just immediately happily ever after, right? (What it most reminds me of is Nozaki-kun, where Maeno said that every manga author should start writing about their own romantic experience, and they all ran away at maximum panic because romance authors have no romantic experience.) It's fine when you're 14, and don't know much about relationships, but as you get older, it really starts to grate, and this sort of thing really is more common in shounen than seinen series.
