From FOOL COOL ROCK! An interviewer has asked ONE OK ROCK, “If you were a family, who would you be?” Tomoya’s answer: “The father would be Toru, Taka the mom, me as the eldest son, and Ryota as the youngest.” This is OOR acting out those roles. For more context to Ryota’s answer, see this previous gifset! Any mistakes due to paraphrasing are mine.
Toru=yellow, Taka=blue, Tomoya=white, Ryota=green.
