This was really cute but not only light-hearted. There's strong sisterly love and a romance I supported. I did not enjoy the teacher-student relationship even after they lost that relationship. I hated the teacher. The older sister showed tremendous growth and I enjoyed the younger sister's checklist. It was nice we had something to follow along to. I love the younger sister, I found her independent and hot. Generally the romances weren't that interesting but I would watch again because of the sisters and that's what this drama is about.
