Intro
Guest is ordinary person,in life,just work,sleep,eat and clean herself.Nothing new,another day is just the same.The same moody and annoying boss.But everyday after work,she would greet her mother,then go upstairs,not to her room,but Keonho's room,where there were many awards for swimming competitions.Then she would remember,how he was used to be when he was still small and young.How his little finger wrapped around hers when he was still a few months old.The room was full of memories,when he was scared of the thunder,Guest would sleep in his room with him.But ever since Keonho became an idol in CORTIS,they rarely seen again.
