Burn
Shamal sighed, rubbing the back of his head as he walked down the hall of Nanimori High, on his way to the doctor's room. It seemed one of Tsuna's friends had gotten into some unknown trouble and Reborn told him to check the patient.
He never mentioned if Tsuna's friend was a he or a she.
As he entered the room, he glanced at the direction where his 'patient' was waiting for him and then closed his eyes before walking over to them.
In a reflex, he placed his hand on the patient's chest, already assuming it to be a girl. He tilted his head upwards, humming to himself as if he were actually checking the patient. He didn't notice Tsuna's stifled chuckle.
Shamal frowned, as he pulled back, still not opening his eyes.
"Not good. I told you, I don't treat boys," he muttered.
"Ah, excuse me, but I'm a girl," a sudden feminine voice came from in front of him and his eyes snapped open. Indeed, in front of him was a girl. The faintest blush of embarrassment appeared on Shamal's face.
He quickly glanced at his watch and widened his eyes.
"It's already this late? Sorry, I've got a date!" he yelled before sprinting off, his face nearly tomato-red by now.
Once he was gone, Tsuna cracked, clutching his stomach as he laughed until he felt like he was having the stomach flu. Even Reborn dared to let a smile appear on his face.
"Burn~!" you yelled before joining Tsuna in his laughter. You didn't mind being used for your flat-chest-ness if it was to embarrass the perverted doctor.
