RING RING! I rolled around sleepily in bed, fumbling for my handphone in the dark. I squinted my eyes to check the time. Eh? It was 1 am in the morning. Who could possibly be calling?

Kangin oppa- the caller ID read.

I furrowed my eyebrows in confusion. Why would my big brother call me at this unearthly time?`

I hit the accept button and placed my phone on my right ear while snuggling further into my bed.

"Annyeonghaseyo Kangin oppa..." I mumbled groggily and covered my mouth when a yawn escaped my mouth involuntarily.

"Oh Yoona ah...can you come over to our house?" Kangin croaked.

Alarm bells rang in my head. "Kangin oppa, gwaenchana?" I asked hesitantly.

There was a deafening silence and Kangin replied, his voice cracking at the end. "I will be but I'm worried for Donghae the most."

Donghae's name flashed in my mind like neon lights and a box of memories I locked in my brain opened.

"Araso oppa...I'll be there."

Kangin hung up, leaving me concerned and troubled about how Kangin sounded like he was choking with...sobs.
