Same here, but in some moments I just can't imagine happy end.

How'd you know?

maaan, I'm not convinced. It'll be a bittersweet ending at most.
Oh. Ok. So tupid of me to not read that. I was so caught up with that image (really adored that attempt to change the atmosphere.) She did mention a happy ending but I guess that's only for now. Though I'd love to see how she'd steer this story into that (and honestly, I'd like to be happy for the characters in the end). I trust that if she wants to, she can do it (I admire her that much). But I get ya and I think, if ever, her bittersweet ending will be good too.
Well.... I kinda believe it will have a happy ending, though can't think of how the mangaka's going to do it. Let's wait for her to surprise us, shall we?
Learning that this will be having a happy ending relieves the hell out of me.
