Light is the root of all evil
Tobirama Senju did not get sick. He got injured, sure, infected wounds too- but never sick.
At least, not since he was around twelve years old.
So, when hewoke up with a splitting headache he promptly ignored it and went right back to work. He'd probably worked a bit too late, it wasn't anything too bad- happened before. It tended to go away in a few hours of rest, which he'd get enough of in his (half an hour) break
The next day, he woke up feeling slightly.... Well, sick.
The third, it got worse but he could still ignore it.
Fourth, he got an urge to puke.
Fifth. He did puke. (No one saw though.)
Sixth. He was feeling rather lightheaded.
Seventh. He fainted.
Well. Guess there would be no escaping his brother's concern now, since he did so in the middle of a meeting.
Tobirama blinked his eyes open then immediately shut them, cursing the overhead lights. It was too bright. Who the hell opened the door to the garden?
He thinks he heard an 'ah' and the soft pitter patter of feet, but he couldn't be sure through the headache he was currently experiencing. His throat felt clogged up, there was a soft ringing in his ears and he felt like he was on fucking fire. Which, as a natural water affinity, he only felt when he was set on literal fire.
(Stupid Uchiha and their stupid fire jutsu. The fact that he was in love with one of them did not stop them from being idiotic.)
Soon after whoever it was finished walking, the door was shut, leaving Tobirama very thankful for the dimmer lighting.
It could still use some improvement as his eyes seemed to decide they wanted to be stabbed (not literally) today, for whatever reason.
Cue a few seconds later and the fairly familiar presence sat down behind him. (not exactly behind him, since he was laying down. Rather.. Above his head?)
If only the stupid haze would go away, then he could pin down whoever it was. Everything felt as if it was through a veil. Well, everything except the stupid light.
(If Tobirama had been in his right state of mind, he would just grumble slightly and proceed to ignore the light, as a sane person would do. Sick Tobirama would like to tell the light to go fuck itself right into non-existence.)
He was swiftly brought back to reality when he felt a pair of hands place themselves over his eyes, shielding him from the light and providing some coolness.
He unconsciously relaxed, slipping back into unconsciousness in a few seconds flat, which could only happen because he was sick. His mind usually had too many ideas running around in it to be able to sleep that easily.
(On another note, he had actually relaxed, even if sick. He most likely trusted the person then, as his honed instincts weren't acting up.)
