It was stated that they went back to their original world since little sister wanted to continue her studies until college. FL and ML also in the modern world while FL went back to the other world every weekend to check on Titania. I just want to confirm, they already spent a season in the other world but it seems like it is only days in the modern time. So if it's time the little sis go back to the other world to help the prince, he might be already the king at that time. Hahaha
