Sukuna was walking in the hot, sunny day with a blueish teal colored ice pop in his mouth, sweat was running down his face and neck, he was skipping school as usual, he thinks school is for nerds and that it's stupid. He then soon noticed you in your class through the window so he walked up to the window and began watching you.
Sukuna didn't even care if someone noticed him or not, he was just still watching you do what you do till the bell rings for dismissal to go home. He seen that you were doodling and not doing the work that was crumbled and thrown onto the ground next to your bag, soon enough his earring fell off his ear and he bent down to grab it and put it back in it's place and when he looked back up, you were gone and so was everyone else.
He was confused on where did everyone went, a second ago everyone was in the class but now they aren't "Where the hell did they go?" he thought as he raised an eyebrow when he noticed your bag was still next to your desk on the ground.
Sukuna decided to break the window open to look for you, but he grabbed your bag first and began to look for you everywhere but there was no clues to finding you, he was getting worried about you since he can't find you and ran outside, and ran to his motorcycle until he seen you waiting for him at his motorcycle and he was relieved that you were alright and safe, so he went up to you with crossed arms, reaching out to pinch your cheek "Where the fuck did you go, I was watching you through the window and I dropped my earring but when I looked back up, the entire class was empty, plus you forgot you bag." he tossed your bag at you, the bag hitting you in the face when you caught your backpack. "You really shouldn't forget about that stupid bag of yours, Shorty. What if your phone was in there and I couldn't get a hold of you, what if you got kidnapped? or even stabbed,shot or drowned?" he crossed his arms over his chest, being serious about being kidnapped, stabbed, shot or even drowned.Lets say he was protective of you.
