What if? (Haikyuu hanahaki)

What if. It's a question that starts a lot of things. Who would have known that such a simple question would lead to such complex emotions?
Oikawa was just thinking to himself 'what if Iwa-chan and I were dating?'
That's all it took for him to start slowly feel weird around his childhood best friend. But he soon ended up falling for his best friend. Hard. One question still lingered on his mind though; 'What if iwa-chan doesn't like me back?'
Next thing he knew, he was coughing up a storm. He rushed out, covering his mouth, and then looked in horror at what he saw.
A single lily petal.
