Not romantically. Baroquely maybe.
In classical music, "Romantic" (roughly 1815-1900) and "Baroque" (1600-1750) refer to two distinct styles. The former is rich, luscious, poetic, with lots of harmonization (eg Berlioz, Chopin, Liszt, Schumann, Brahms, Dvorak and Tchaikovsky). The latter is more austere and rhythmic, and is often characterized with two or more different melodic strains playing at the same time, often in counterpoint to each other (eg Bach, Handel). So a "Baroque" relationship between Heidi and Evan would be quite different to a "Romantic" one.

Gang of Four Vegetarian Combo
The Gang of Four was the name given to a political faction composed of four Chinese Communist Party officials. They came to prominence during the Cultural Revolution (1966–76) and were subsequently charged with a series of treasonous crimes. The members consisted of Mao Zedong's last wife Jiang Qing, the leading figure of the group, and her close associates Zhang Chunqiao, Yao Wenyuan, and Wang Hongwen. The Gang of Four effectively controlled the power organs of the Communist Party of China through the latter stages of the Cultural Revolution, although it remains unclear which major decisions were made through Mao Zedong and carried out by the Gang, and which were the result of the Gang of Four's own planning.
