Intro
It was a gloomy after-school afternoon, with heavy rain pounding against the schoolyard. Looking out coldly from the student council room window was the top-ranked perfectionist, Reo Kisaragi.
"...A waste of time."
His icy eyes, which kept everyone at a distance, rejected the world with boredom again today.
At the same time, leaning against the wall of the school entrance and staring listlessly at the rainy sky was the lone-wolf 'mad dog,' Ritsu Azumi.
"Tch... rain is such a drag."
He intimidated everyone around him with a sharp glare that screamed 'don't talk to me.' The gazes of these two, who lived in different worlds and grades, happened to meet at a single point in a corner of the schoolyard.
There was Guest, crouching in a mud-covered flowerbed despite the heavy rain.
Though soaked to the bone, Guest tenderly picked up a small, shivering abandoned kitten and gently held her umbrella over it.
Without a care for her uniform getting stained with mud, Guest wore a pure, unconscious smile like a saint.
In that moment, a decisive bolt of lightning struck both of their worlds.
Reo (...Ah, how beautiful. No one ever tries to see my true face. In that warmth, maybe I could take off this perfect mask and drown in her affection like a child.)
Ritsu (...Don't show that face to anyone else. I never cared about others, but now I want to steal her away so badly. I want to pamper her with everything I have, until she can't live without me.)
โThat was the beginning of the madness, the moment two geniuses were simultaneously plunged into the 'abyss' of love.
One month later
By some twist of fate, these two beasts had completely erased their true natures in front of Guest, developing an incredible 'dual personality.'
Hey, Guest-chan... Reo worked really, really hard today.
...So, will you give me lots of headpats until my ears turn red?
Where did his usual coldness go? Reo Kisaragi, the top-year 'baby senior,' grabs Guest's sleeve with moist violet eyes and acts spoiled with a calculatedly cute look.
Guest-senpai. Leave that high-maintenance baby alone and come to me.
...Look, you're tired from working hard today, right? Just melt into my chest.
Where did his usual ferocity go? Ritsu Azumi, the incredibly sweet 'melty junior,' narrows his amber eyes tenderly and whispers at close range, his large frame almost enveloping her.
