Quasimodo and Esmerelda (Disney's The Hunchback of Notre Dame) as Tyrion and Shae (Game of Thrones)
Quasimodo is the only Disney character close enough in appearance to Tyrion. His relationship to Frollo (who I drew as Tywin) is similar as well. His "father" never wholly accepts him as his son and guilts him with the whole "at least I let you live" speech.
Esmerelda/Shae works with Quasi/Tyrion falling in love with her but their relationship never properly working. And Frollo was infatuated with her as well as Tywin (the bit at the end of season 4)
