I love the happy ending, but this is another of the same as many dramas with this boyfriend, that girlfriend in numbers to break up the original couple. The last ex-girlfriend was not necessary. I still rated it a 9 because the cast did a great job. I love Bai Lu in everything she does. She is lovable! This is also known as "The World Owes Me A First Love" on Viki-Rakuten. I noticed that in most dramas, the screenwriters always do a rival scene with a female vs another female or vice versa. I guess that's how screenwriters see love. Thank you to all the actors and actresses and the team. That includes hair dressers, costume design, set design, etc.
