1. Both of these dramas have the sweet, light-hearted content and based on lives of college/ high school students. In "To the beautiful you", Kang Tae Joon (Minho Shinee) is a high jump competitor while Kim Bokjoo (Lee Sungkyung) in "Weightlifting Fairy" and her partner, Jonghyun (Nam Joohyuk) are majored in weightlifting and swimming in respectively.
2. The main male leads are both known as the "hot boy" at schools with handsome look and amazing talent in their own majors. Somehow, they also struggle with their sporting career. If Kang Tae Joon got an accident that could potentially ruin his future career as an athlete, then Jonghyun's trauma is the only thing that gets in the way of his success.
3. Kang Tae Joon and Jonghyun each used to be really cold-hearted until the female leads come to light up their worlds.
4. There's always a second female lead who had a relationship with the main male lead- "To the beautiful you", Seol Hana (Jiwon) is his childhood friend and loves him for a really long time while Siho (Soojin) is his ex-girlfriend who still has some feelings for him. Both always try to annoy the female leads.
