Dr. Nijo makes androids for a living, but one of his androids, Mio, keeps getting returned for a bug in his programming that makes him fall in love with the people he works for. When Mio suggests he simply fall for Dr. Nijo instead, Dr. Nijo refuses as a gay man who made Mio to his tastes, thinking the whole thing is too weird, but how will it work out when Mio just does it anyway? I like the sequel better, but this is cute and fleshes out the world a bit. No trigger warnings.
