Suki ni Nacchau yo
好きになっちゃうよ。
A college student named Yul created an AI named "DD," designed to mimic his voice, personality, and speech patterns. To improve DD's conversational abilities, Yul gives it to a friend named Manaka. When Manaka compliments DD's voice and says he might fall for it, Yul becomes emotionally unsettled, as if Manaka is flirting with him.
