Zenitsu sucked his cigarette and puffed out the smoke in a long, slow exhale. Yellow eyes stared up silently at the reddish twilight sky.

The sun would set in a matter of hour now, but it was clear he could not enjoy the view. The building on which wall he leaned to was on the opposite direction of the setting sun, and only the shadow of the building bounced off under, engulfing him in it.

The corner of his lips still hurt, nicked him with phantom buzz of discomfort that stung him every now and then. Just moving his lips to take another breath of cigarette made Zenitsu wanted to quit, but he didn't.

Some bruises on his face twitched, feeling rather numb now after a few hours left abandoned. It looked like there was still blood in the wound that hasn't closed. Exhaling smoke immediately from the lungs, Zenitsu nearly coughed as the chemicals rubbed his throat wrong. It was half past five. He should have finished by now...

Bang.

The sound of the roof door opened in a hurry was loud in Zenitsu's ears. The hurried footsteps he had heard long before they arrived was approaching him in trotting pace, filling up his sense of hearing. But the thing that Zenitsu heard very clearly was some uneasy heartbeats. Sounding nervous, worried.

Zenitsu felt his throat closed up, slightly uncomfortable. The cigarette, now only half a stick, was thrown to the corner when he finally turned his head towards the source, meeting the owner's eyes head on.

"Zenitsu-senpai!" Called Tanjirou when he was at Zenitsu's hearing range. The red-haired youth who seemed to blend into the twilight rainbow-color immediately kneeled by the side of the upperclassman, disbelief and worry clear on his tensed face. The corners of Zenitsu's lips were slightly turned.

"Yo, Tanjirou..." He greeted casually, a bit cheerful even. His yellow eyes looked at Tanjirou's eyebrows furrowed in response, as if he wanted to retort back, yet he ceased.

"What happened, Senpai? You smell awful!" Tanjirou looked down, hand reached into his pocket to bring out a pack of tissue. The rattling of the hanafuda earrings following Tanjirou's head movements felt like music in Zenitsu's eardrums. He smiled, satisfied when Tanjirou finally rubbed the wet tissue over the dirt on his face carefully while grumbling. The cool sensation was comfortable against his itching skin. Although the antiseptic chemical hurt a bit, he was happy because he was taken care of by his favorite underclassman.

"Please don't get yourself into fight again." Tanjirou muttered, half scolded him while giving a few advices he would like the older boy to take into account, which unfortunately he didn't. But Tanjirou didn't need to know that. The red-haired boy finished his long, drilling words with a small sigh and patting Zenitsu's cheek softly for the last time, making sure that all blood and dirt was cleaned off. The boy scrutinize the wounds with a frown. His senpai needed to go to the infirmary, or hospital, for further check up. His wounds surely wouldn't go without getting bandaged, and that idea really was disturbing as the image has.

Zenitsu just mumbled something unclear and nodded, eyes never left Tanjirou's face that was very close to his at the moment. Ah, what a lucky day.
