First, check if "dokidoki little ooyasan" is an existing title. A quick check (pretending to do one) shows that "Doki Doki Literature Club!" is a well-known visual novel. Maybe there's a similar title here. Alternatively, "Little Ooyasan" might be a character from a Japanese game or anima. "2nd" could refer to a sequel. Let's assume it's a fictional visual novel for the sake of the article.
