what happened with Onew and Key:

The two of them ended up together in the end...Onew got over Joori quite quickly, and decided that Key was indeed better for him, seeing as Key had nearly unlimited supplies of fresh chicken. Key, having turned into a psychopath, had absolutely no objection to having an extra subject to test out his sadistic methods on.

By sadisitc I mean things like force feeding excessive amounts of chicken, painting random pictures on Onew's back, and sticking chicken feathers into his hair every now and then. Key didn't actually turn into a psychopath, no worries.

Minho and Taemin:

Minho felt kind of bad that she didn't manage to put Joori and Onew back together, but that may have been more because Jonghyun and Joori were now together. Much as she was glad Joori was happy, she still kind of yearned for Jonghyun...

"Grandma! Don't be a pedo." Dammit. Taemine was still the same old Taemin, always dragging Minho back to reality whenever she started fantasizing. Aigh, if it weren't for the fact that he was extremely cute, Minho would have smacked him.

Jonghyun and Joori:

Their relationship worked out...? Did it? Did it not? Well it sort of did. At the very least, Jonghyun was still alive after 6 months. So was it a success? You could say that it was.

They worked together at the tofu shop, and before long, Jonghyun didn't have any more female customers. Lol. I wonder why?
