Is Sexbomb's Daisy Siete plagiarizing Korean Dramas?

Sexbomb's Daisy Siete is becoming more intriguing and confusing.  Why?  Because back then, I don't care where they get their drama series' concepts and stories but now since I'm a Kpop fanatic and seen lots of Korean drama, I am aware that they have been copying Korean drama series.  Their last season of Daisy Siete - "Bebe and Me" was the same as "Witch Yoo Hee"  but with some twists and turns and more characters involved.  Rochelle Pangilinan portrayed same character as Han Gain's, a woman with a strong personality who always wear black, met a guy from an accident and made him pay his debts by working for her as all-around personal assistant and so on.

Now their upcoming series Daisy Siete - "Adam or Eve" was taken from one of my favorites "You're Beautiful/ You're Handsome".  The story was almost the same, Rochelle Pangilinan's character will play Park Shin Hye's character who spend her time in church/monastery but a misfortune happened to her twin sibling and needs her help.  She had no choice but to help her sibling and pretends to be his twin brother and join the boy band.  I'm sure there are twits as well but the big question is -
