"Are you advertising?" I wanted to ask this question for the whole time the last episode of "The Heirs" was playing. The last episode of "The Heirs" seemed as if it was a twenty hour long advertisement medley.

Pay Per Lead (PPL), which refers to a type of affiliate marketing program where the advertiser pays the affiliate based on conversion of leads, in the case of the drama "The Heirs," such as the number of times the specific product showed up in the drama.

Especially because "The Heirs" is based on the lives of the high school sons and daughters of the conglomerates, the number and quality of products for the pay per lead advertisement was incredulous. If there was a prince on the white horse back, in "The Heirs," there is Kim Tan riding a luxury sports car. Audiences will also remember the "X boy," which made its appearance throughout the drama. Kim Tan's mother Han Gi Ae, played by Kim Sung Ryung, used to learn English with it, and Choi Young Do, played by Kim Woo Bin, used to study Cha Eun Sang with it. Even Kim Tan, who always sought classical, minimalistic fashion, wore a necklace from one designer brand with his school uniform, attracting the attention of the audiences.
