Kyungsoo and Lee Hayi are childhood friends, they've been together for as long as both of them could remember. Although Hayi is 2 years younger than Kyungsoo, they both blended well. Kyungsoo loves to cook and Hayi loves to eat. At times,when in awe of what they are watching,  Kyungsoo will be wide eyed, whereas Hayi would have her jaw dropped. There are things that are pretty much awkward between them,some matters that they chose not to confront,  but most of the time they compliment each other. 

For their classmates that the two are inseparable, there at times wherein some people say that they are twins, for there are some similarities in their features. Their families approved their friendship, for when they are fun to watch. 

As Bom said, (Lee Hayi's elder sister), "such young love should never be forbidden, i'll become the bridge to their success! Plus Kyungsoo's cooking is really good though! Yum yum yum! " 

Kyungsoo's POV

"Ah youth, lovely, lovely, it was a beautiful first snow isn't it? Ah, Tabi I can't wait for you to come home. Our baby Hayi is now a lady." Bom Noona said as she pinched Hayi's cheeks. 

"Yah, Unnie. Do you want me to spill your secret dreams and fascinations to your knight and shining armor TOP from the kingdom of Bang, big and bang! " Bommie Noona's face paled and sweatdropped

Hayi's gaze to Noona was shifted to me. 

"It's your fault Oppa!" She said

"Ah, neh it's my fault, Mianhe." I scratched my head.
