Small fluff headcanon for SukuGo: Even when they were forced to break up due to circumstances out of their control, Gojo still calls Sukuna "Pink/Pinky" a pet name he loved for Suku, and Suku pretended to hate it the whole relationship. When Sukuna is too busy to meet up to hang out, Gojo sends him the good ol "You're breaking my heart again, Pinky 💔" Sukuna calls him to berate him and reschedule, but despite not being together, they always end the call with an affectionate, "I love you" 🥲
