Prologue: 

"Waaaahh!  A flying cockroach!" Hyunseung screamed while circling the room.

Gi Kwang entered the room as fast as he could.

"Where?!"

"There!" Hyunseung answered while holding a pillow sitting down in the corner far away from the cockroach.

Gi Kwang saw the cockroach and killed it with his sandals. He looked at his sandals and held the cockroach with his hands. 

"Is it dead already?" Hyunseung peeked from his pillow.

Gi Kwang went closer with his hands on the back.

"Yeah~"  When Hyunseung took off the pillow in front of him, Gi Kwang faced the cockroach to him.

"Yaaaaaaaaaahhhh!!!!!!"  Hyunseung ran outside from his room leaving Gi Kwang who's laughing so hard.

Gi Kwang and Hyunseung have been best friends since high school. They met at their school's garden where they always express their feelings. Fortunately, they are also roommates. When something happens to Hyunseung he is always there. He is like the knight shining armor of Hyunseung, even though he's older than Gi Kwang. Until one day, Gi Kwang has to go to Japan because his mother and father decided to live there for 2 years.

~Airport~

"Don't worry, I'll be back for you I promise." Gi Kwang hugged Hyunseung.

"I want you to be happy while I'm gone." he continued while wiping his tears.

"Who *sniff* will be there *sniff* to protect me? How can I live without you?" Hyunseung cried.

"You can do it. I know you can." Gi Kwang wiped Hyunseung's tears.

"Dear we'll be late!" his mother called.

"Okay I'll be there!"

"Bye Gi Kwang, I'll miss you" Hyunseung cried like there was no tomorrow.

"I'll miss you too. I'll be back just wait for me." with those last words, Gi Kwang hugged him and waved a goodbye.
