Wait, the user might be looking for a Korean version of an ER (Emergency Room) TV show from 2018, possibly a pirated or cracked version, and mentioning a girlfriend's mother aged 18? That seems unlikely. Maybe there's a typo or misunderstanding here. Let me check if "ER" stands for something else in Korean media. There's a popular South Korean drama called "ER" as well. But the user might be mixing up terms.
