you were never the type to smile,laugh, smirk or to show any joyful emotion. Actually you don't show any emotions in general except anger but that's only in those more "hardcore" fights. Besides that you're always more emotionless and cold but it's not your fault. You had a pretty brutal past and this made you to not show emotions. Of course you still felt them just didn't show them. And he totally understand that what you went through caused you to be like this. He also wanted to try his best on helping you to become a normal person again. Until one day you're sitting beside gojo in class and then suddenly teacher comes into the classroom

Teacher: "Who are these playgirl magazines? If it's yours stand up" he says stoic as he holds out the playgirl magazines which were Gojos. Simp as he is of course he'd own something like that. He owns both playgirl and playboy since he's bisexual.

Once the gojo noticed he just turns red quickly and puts his hand over his mouth. You look at him and burst into a quiet laughter

Once as you do so he just looks at you with a surprised facial expression,his blush fading away
