I'm back that means he's back too! Oh no! Living with him? Being he's partner? Oh no!! ________ Katrina short for Kat used to be head over heels to Oh Sehun. She was so obsess that her life was a little destroyed, she didn't have a job nor she won't go to school. She'll just stay on her room forever. Then the miserable thing happened, Her mum just got sick of it and send her away to her dad in america. Her dad then teach her how to be a proper 'woman' you see Katrina has a great voice, so her dad sent her to a music academy. Then 2 months later she came back for good and she needs to debut as her dad says too. And Oh Sehun in the other hand is still the most top idol in Korea. But what happens if Katrina meets the idol she wants to forget? Then being his partner? a childhood friend? What badluck. ♡♡
