AS A PAIR OF CERULEAN BLUE EYES STARED AT HIM, y/n was happily polishing his sword as he felt uncomfortable with something, though, he couldn't pinpoint on what, he turned around, but to always see nothing there. "he's so pretty," she gasped at him. y/n sheathed his blade before humming and walking his way towards where the girl was, the girl squeaked and she dusted herself neatly before smiling brightly and walking towards the boy. 

"hello y/n-san," she greeted formally. "ah, aoi-chan," he smiled softly at her. she blushed bright red. 'he called me by my first name!' she said before smiling up at him. "how is your recovery going?" she asked as y/n shrugged. "the usual, it's getting better," he said happily. aoi sighed in relief. "glad to hear that-"

"y/n-san!" a squeaky voice called when y/n turned around to face a girl with black hair and black eyes. "ah, yuki-san," y/n said happily. "how is your recovery doing? i brought you this by the way! i made it!" yuki exclaimed happily as she gave him the bento box that she held. y/n took it from her hands and smiled brightly at yuki. "thank you so much, yuki-chan!" y/n exclaimed with bright eyes as yuki blushed shyly. 

aoi's hands clenched into fists as her eyes twitched in anger before she thought of a sinister idea. though she knew it was against the rules, she couldn't help it. she was deeply in love with the boy and is willing to do anything to make him like her back, to even say, she would even kill for him. "hey guys, wanna have tea tomorrow at three?" aoi tilted her head as she smiled fakely. 

she would kill anyone who dares to talk to him with a blush. "that sounds great, aoi-chan!" y/n exclaimed brightly. "sure, why not?" yuki smiled happily. a crow was seen lingering on top of the three. "southeast! yuki! go to southeast!" the crow cawed before it flew away. yuki sweat dropped. "right! i have a mission to go to, i'll see you both soon!" she exclaimed before she walked off into the distance. "do you want to have lunch with me, aoi-chan?" y/n asked as aoi looked at him before beaming brightly. "of course."

the both of them sat on the engawa as they ate their food silently, aoi leaned on his arm as she smiled happily and y/n didn't bother her being so close to him all the time. "and then the demon was screaming in pain, and the end," y/n said before he finished the last bit of the bento box. "really now?" aoi asked. "you're stronger than you look, y/n-kun," she said happily as y/n smiled. "thank you," he said before he stretched. 

he looked up at the bright sky as he admired the clouds. "such pretty clouds," y/n muttered. "indeed," aoi said as she looked up at the sky. "such pretty clouds, but none of them are prettier than you, aoi-chan," y/n smiled happily as aoi felt her cheeks flared red. y/n chuckled as aoi looked away silently, huffing.

"i love you, y/n-kun!" a girl exclaimed as she bowed in front of him. aoi watched silently from the bushes as she felt her eyes twitched in anger. "sorry, but... i like someone else," he said silently before the girl straightened her posture and stared away from y/n. "a-ah, i see," she said silently. "c-can i know who it is at least?" she asked as tears glistened in her eyes. "it's aoi-chan," y/n said before aoi's eyes widened and she felt her heart race even faster. 

"she must be lucky.." the girl sniffed before y/n placed a hand on her back. "i'm sorry," y/n said silently as the girl nodded. "i hope you have a bright future with kanzaki-san, i'll go now, thank you for your response," the girl said a she walked away silently. though aoi was filled with ecstasy, her heart burned in jealousy and malice.

"i heard that you confessed to y/n-kun earlier," aoi said as she smiled softly at the girl. the girl's cheeks flared up red. "who told you?" the girl asked silently. "ah, just one of the butterfly girls," she said before she gave her a box of mochis. "for you," aoi smiled. "ah, thank you, aoi-san!" she exclaimed brightly as she grabbed the box and started eating the mochis before she smiled happily. "it tastes so good!~" she cooed before she started feeling that her face was bruising and rotting. 

she suddenly choked as her lungs shut down immediately and aoi grinned, laced with malice. "he's mine. back off." the girl's eyes watered as her whole body suddenly turned purple, her flesh rotted as her skin felt like it's burning, blood vessels exploded as she fell on the engawa and she slowly and painfully died out of poisoning. aoi grabbed the rest of the mochis before leaving the girl's corpse on the engawa of her house.

y/n hummed as he sat on the dining table with yuki, across them, aoi was sitting with her eyes twitching annoyingly. aoi offered yuki the tea cup as yuki drank it before muttering a thank you. y/n smiled at aoi. "thank you, aoi-chan," he said brightly before aoi gave him his cup and he gulped it down. "oh, no problem," aoi said before yuki smiled at her. 

a few minutes later, they engaged in a light conversation before yuki choked. her skin was turning purple as aoi smirked knowingly and y/n's eyes widened in shock. "yuki? hey, yuki! what is happening?" y/n asked as he held her back and yuki continued choking as she felt like she's internally bleeding, her skin was rotting miserably before she died in the hands of y/n. "yuki? hey! yuki, wake up! this is not funny!" y/n exclaimed in shock as he tried shaking yuki awake, but there was no response. 

"my, my," aoi said as y/n turned to her. "such an amusing sight, you and me can finally be together now y/n-kun!" she exclaimed as she stood up from the table and walked towards him, slowly wrapping her arms tightly around his torso. "i've finally gotten rid of the problem."
