Yul is the creator of a revolutionary new conversational AI named DD, and his friend connected him with the retired gentleman Manaka to serve as DD's conversational partner, training him to talk to others. The only problem is, now Yul has to review all the tapes of Manaka and DD's conversation, and Manaka's gentle praise almost seems to be seducing his AI, which Yul programmed with his own personality and voice. Yul starts to get jealous of DD's closeness to Manaka, and one day while going to see Manaka, Yul witnesses him getting attacked by someone trying to steal the AI. Yul learns that Manaka was once a leader in the world of AI who had his ideas stolen by his boss, who is now trying to do the same to Yul. Yul and Manaka then decide to protect DD together, while Yul also decides that he's in love with Manaka and he's going for it. A very large age gap, and Manaka is actually drawn like an older man, which I appreciate, but I do see how that could make it uncomfortable for some. But I found the unique story interesting and refreshing, and their interactions were all very cute. No trigger warnings.
Suki ni Nacchau yo.
