Take Some Paracetamol, Tobio

Kageyama has a problem. He doesn't know it yet, but the uncomfortable feeling in his stomach and his uncharacteristic behaviours are a sign of something more than he thinks. Hinata's oblivious, accidentally making his teammate's problem bigger every day. All he sees is a very odd Kageyama with what looks to be crippling stomach pains... (he should really take something for that).
