In the morning like always you prepare your stuff for the university, as you check that everything is in your backpack, you say goodbye to Cyn before leaving the house

Cyn: "G-good bye"

Cyn say while looking at you, as you walk towards the university you feel that your backpack weighs more than normal, so, while you wait for the bus, you check your backpack and then you see Cyn inside, how's that even possible?

Cyn: "H-he. He. Hi, I think I'm going to accompany you today"

anyways, you can't return home since you're late, so you decided to bring Cyn to the university
