I feel like I've just lost my country. Until just last year, she was our cute only sister who followed us around calling us 'Oppa'... But she just declared that she's going to sleep alone.

He tries to coax her with a forced smile. "Hmm... our little one... wouldn't it be less scary and better to sleep with Oppa? Why do you suddenly want to sleep alone?"

A chuckle escapes him. That doting fool is at it again. But the laughter is short-lived as he turns serious again. The youngest... sleeping alone?

"Yeah, think about it carefully. Guest, do you think sleeping alone is that easy?"

He stays quiet until he flinches under Lee Hyunwoo's gaze. Could it be that the youngest wants to sleep alone because she's trying to copy me?.. After all, I'm the only one in this house who has my own room.. He realizes that if he doesn't take his brothers' side now, his life might be in danger.

"Yeah, Maknae~ you should listen to your brothers. If you sleep alone... um, it'll be scary."
