Sweet Experiment With My Sugar DaddyEpisode 3

Eileen, a brilliant physicist, is betrayed by her cheating boyfriend Julian, who sells her four-year nuclear fusion research to an arms dealer and gets her expelled. Desperate for surgery money for her dying father, she accepts a one-year “exclusive companion” deal from mysterious Alexander — who turns out to be the boy she once accidentally sent to prison. He has watched and protected her for 14 years. He rebuilds her lab, recovers her data, but their painful past fuels misunderstandings. As Julian and the arms dealer strike back and a criminal underworld arranged marriage threatens to take Alexander away, he chooses war over politics, confesses his love, and they sign a new contract: “indefinite and unconditional.” From a deal built on money to a promise built on love.
