Sissi

The young Bavarian princess Elisabeth, nicknamed "Sissi", travels to Austria where she meets Emperor Franz Joseph I at a spa town and falls in love with him, despite their initial secrecy due to her royal status and his engagement to her sister Néné, who is revealed as the reason for their meeting. Sissi's loyalty to her sister forces her to reject Franz Joseph's confession of love, but he defies his mother's reservations and announces his betrothal to Sissi, leading to a wedding ceremony in Vienna.
