A Similar Scene
I spotted a similar scene while watching My Better Half Episode 14 where Teresa (Gigi) confesses her love to Michael. She confesses without talking but writing it down on a huge notebook. And the similar scene is!! Linda Chung's Miss You Day And Night MV. They both wanna confess because they don't want to regret it since the 'guys' in these scene already have a girlfriend.
She starts talking about how she was mad but she was hapy for him that Yuki (Mandy Cho) came back to him.
