Of course, Mori doesn't fall for it at first glance.
"Taaakashiiii!" The sing-song voice rises with every syllable, a fount of chocolat crème and marron glacé softening the sides of his cousin's mouth. "See? No more toothache! I'm cured!"
Grins and exclamations galore. He brushes them aside.
Mitsukuni holds up his spoon. It's carved from nothing but the finest Venetian silver with swirls of petals etched into the handle. Naturally, the little blond is blind to such aesthetics unless it's the deliciously smooth curve of the chocolate delight ensconced in the bowl before him. He dives and Mori starts counting to three very slowly.
A munch equals one second. At two, Mitsukuni stops in mid-chomp.
Mori never gets to three, given that he has to find a clean hankie for the tears that ensue and a suitably straight face to keep the act intact. The girls love it, alternating screams of laughter and squeals for the entertainment. Mitsukuni refuses the menthol band-aid for his throbbing jaw and Mori endures a fierce kick to the head for his troubles.
As planned, Mitsukuni will burst into more tears later on and apologize with much childlike aplomb before a dewy-eyed audience, earning them more sighs and swoons than all the chocolates Tamaki receives for White Day. Frankly, Mori knows that Mitsukuni would prefer the chocolates to the girls but he's not going to bother himself (or the latter) by reminding him that that day is indeed today and not next month. Valentine's, that is. The performance may not have been real but Mitsukuni's toothache is very much so.
"Taaakashiiii!"
Mori does not ask why or how Mitsukuni sneaks into his room later that night. It is two o'clock in the morning, he had been enjoying a particularly nice dream about climbing the mountains in Hiroshima and his eyes are now itching from being awoken but that is beside the point.
"What is it?"
The tears well up again, rendering honey-brown eyes murky as mud. "I'm so hungry, Takashi! Do you have any food around? They've locked the pantry in the kitchens!"
"I have some oranges in that basket over there. Or some gum in my desk…"
"Not that hungry!" He sniffles louder for effect. "Father forgot my sweet ration for the day."
Without a sound, Mori reaches into his bedside cabinet and pulls out a bread roll from the stash inside. He doesn't much care for the sweets but he knows how much Mitsukuni enjoys the sweet splash of raspberry jam on his tongue.
"Yaaayyyy, thanks so much, Taka –"
The rest of his name swallowed along with the confection.
Mori knows he is going to wake up tomorrow with Mitsukuni still slumbering by his side, his sheets full of breadcrumbs and red jam spots on his pillow. He knows that indulging the boy is his only weakness. Wholly much so.
He doesn't quite mind.
Mitsukuni will surely forgive him for the White Day mix-up on his calendar in the morning.
