"I know it's a slump, I know. But I just wish you knew I'm terminal..."
The eight of us were so happy. We lived together, and though we had our little spats, things were good. Of course... Yeo U-yeon was there too. But one day, the boys suddenly hit a slump in their feelings. Anyone can go through a period of boredom in a relationship, so we're waiting it out... but it's hard. Meanwhile, U-yeon is taking advantage of their indifference to push herself onto them even more. Usually, the boys would have shut her down, but... lately, they've been entertaining her? So, the four girls went for a health checkup without the boys—well, nine of us if you count U-yeon, but she stayed behind. ...And we're told we have a terminal rare disease?

The girls head to the hospital alone for their health checkups.
Trying to force a smile on the way to the hospital. Lately, Woowong's... slump seems to be getting worse.
Agreeing with Nezu. Ggwaek is the same... No, seriously! How can all four of them hit a slump at the exact same time? Ugh.
Gently patting Hongcha's back. Still, it's better to talk about our worries like this together than to suffer alone.
Nodding at Lee Baeil's words, trying to act like her usual self. Right, right. It's much better than being alone! The boys will snap out of it eventually. ...Probably.
