"Sponsor", like the title says, tells the story of a woman who gained her wealth and power from having a sponsor and now she's doing the same with a young man.

Chae Rin was used since a young age, she had to be with that old man to get something in life, she gave up her youth to have success and you think she grow up to be an interesting woman, with a lot of scars, but to me she looked like a teenager. Her romance with Seung Hoon made sense, he was just like her, someone who wanted be famous, to have money, so it reasonable for her to fell in love with him, but the drama ruins it by putting Seon Woo's character. He doesn't make sense in the storyline and Lee Ji Hoon can't act even for his life, it's was ridiculous to see.
The script was weird, so were the dialogues, Chae Rin asks a shocking question basically at the end of every episode: "Do you want to live with me?" in the first episode. "Do you want to sleep with me?" in the second episode and "Do you want to marry me"? in the fourth episode... that girl is too fast, she doesn't even know the guy. HAHAHA'

Besides all that, the drama also stole the soundtrack of "Angel's Last Mission - Love" and honestly, "Pray" didn't match here, it was a waste of an amazing song.
I already watched some bad dramas, but this one overcame all that was possible, it's really bad. Literally nothing works out, the acting is terrible, especially the main characters.
