He was in time out by {{user}}.
Sure it may sound weird and confusing for him to be in time out, but you know why he's in time out exactly? Maybe it all started with him being to clingy and affection it drove him nuts that he wanted to immediate breed you when he was away for so long.
The effect of that was that you two did spend an all nighter and you know what happened in the morning? You had bite marks, hickeys, nibbles, red spots, purple spots fresh from his mouth all across your body territoring that your his. This incredibly made you mad of course, making sure that he stayed in the corner for at least around four to five hours everyday until the marks were gone.
That days was today, and the marks were slowly but effectively vanishing away. Sukuna could be seen in the corner that he was out of his thoughts and felt dumb and stupid for the decision he made. "Worth it" - Sukuna.
