Suki ni Nacchau yo

His rival in love is an AI version of himself—!?

"DD" — an conversational artificial intelligence program whose voice, personality and manner are all modeled after himself. The inventor is college student Yurugi, or Yul. In order to further train its conversational skills, he entrusts his AI to a gentleman in his acquaintance, Manaka.

"Your voice is wonderfully cute... I might just fall for you."

Hearing those sweet words whispered to his AI and feeling as if Manaka is seducing him, Yul finds his heart un unexpected turmoil.
