The manga sounds like "Dekoboko sugar days"(there was a black haired guy with milk carton)
Though I'm not sure about the test papers..
I don't know about manga but feels like it's a Haikyuu DJ XD
Does anyone know a yaoi with a cover of two boys. One black hair and an orange head who is hugging him. And the boy with black hair is holding test papers and flavored milk cartons. It’s on the last page of the yaoi called our previous existence.
