Title: Blanket

Setting: It was in the very early morning where Okuda fell asleep with a rack of test tubes on the table.

Characters: Okuda Manami and Koro Sensei (who happens to be there)

"…uda-san."

The bespectacled girl stirred in her sleep and so, she slowly opens her eyes with drowsiness. She was staring back to a small pair of eyes which belong to yellow octopus who was wearing his usual cheerful smile.

Her homeroom teacher.

"Why are you sleeping here, Okuda-san?" asked Koro-sensei with worried tone.

Okuda was baffled. It's maybe because she just awake, his question isn't completely registered in her mind. After a few second or so, she looked around her where she saw a rack of test tubes and sort of varied chemicals lining in the room. She noticed she was still at the chemistry laboratory to test new chemical she stumbled upon while browsing the Internet a few days ago.

Plus, she even was going to make someone's request regarding chloroform but she couldn't put her hand on who was it asking her to do so.

She smiles bashfully at his question. "I must fell asleep while waiting for the reaction to happen." Okuda replied – unaware of a black sweater that wrapped around her shoulder when she arched her back to relieve muscle strain as the cloth fell onto the floor.

Koro sensei took the sweater that fell on the floor and gave it to her with grimaced. "Ah, you must not do that, Okuda-san especially at a deserted school building like this all by yourself. Thank goodness I keep my eye on the surrounding in case any unwanted intruder breaks in."

Okuda accepted the sweater with puzzled – wondering whose it belong to. She looked up with guilty expression. "I'm sorry Koro sensei. It won't happen again next time."

"You're working here all by yourself?" He asked – wondering where the red-haired boy went to. He usually accompanied her to create some nasty pranks which bring chill to all their classmates.

She shook her head. "It was supposed to be with Karma-kun but he had to leave in midway because of an important matter to do he received at the last minute." Answered her with cheerful voice.

Koro sensei nodded, accepting her answer. "Oh, well! You should be go home now or your parents would be worried but I bet they are now unless you informed them first hand. Be careful on your way home then."

Okuda was beaming at him. "Hait!" After clearing up the table and placing back the test tube at the rack, she grabbed her bag underneath the table and bid him goodbye. The door closed behind her with soft thud. Koro sensei could only watched her disappeared from his sight as he continued reading the reference book he bought from nearby store.

On the way home, Okuda was trying her hard to remember whose the black sweater belong to when the familiar scent catch her nose.

"Ah, Karma-kun! Silly me, he was the only one who was wearing this sweater. He must be stopping by last night. I'll give the chloroform to him on Monday. Moreover, the result of using smoke bomb containing BB pellets must be intriguing him." She grinned almost mischievously.

Holding the sweater close to her body as his scent swept her nose, her cheek smeared with tint of red. "He is such a nice person." Muttered her softly.
