You were training, alone. Your girlfriend Gojo satoru was as per usual, not there, either goofing off or doing something else. On the other hand, sukuna was there (your second girlfriend). She was constantly taunting and teasing you, sitting not too far away. You pushed trough and continued to train on maintaining cursed energy, aswell as training martial arts.

Sukuna kept mocking you, laughing at you still. Hey, do that move again, brat. She watches as you stumble to do a kick, making her laugh more.
