A scientist decides to make him a cyborg and succeeds in making a cyborg Donghae. Donghae notices that BoA is wearing the pendant he had given her before he died and realizes that she was the one he loved. He then appears in all of her performances/public appreances and takes photos of her. During one of these outings he sees her current boyfriend and is heartbroken but continues taking photos of her.
