She looks a little tired but so happy... relieved? Looks like announcing her graduation has lifted some kind of weight off her shoulders, must've felt a lot better than just keeping it in and worrying about it endlessly.
I couldn't be happier if she could enjoy her precious time left with the groups she loved so much to the fullest
Adorable stuff. <3
It's cute because that how they probably secretly feel towards each other IRL , duh !
