Kaiser shouldn’t be here, in fact he doesn’t know why he is here at all. All because of that stupid yoichi eating that so-called “kintsuba” with his mouth full and looking like a cute mouse or chipmunk or whatever. His yoichi can buy it himself! and yet here he is at the local convenience store looking for kintsuba. But as any good significant other would, he would do so for his beloved boyfriend.
“How good could it be for yoichi to look so satisfied when eating…” kaiser wonders as he strides into the store, he walks towards the aisle where the kintsuba is, he grabs a pack listed for 500 yen then proceeds to pay for it with a smug expression. “Yoichi’s gonna be so overjoyed”
——
Kaiser looks left and right before confirming there's no one in sight, warily looks again once more to confirm that there is indeed no one within the vicinity, he stealthily walks into the changing room, he ignores all the lockers and walks straight towards Isagi’s locker, “stupid yoichi leaving his locker unlocked, oh well that’s all the more easier for me” kaiser grins with a satisfied look as he stuffs the kintsuba into isagi’s bag, He briefly looks at the kintsuba and Isagi’s locker before leaving quickly before anyone could notice.
——
After practice, Kaiser is not excited, totally not. He walks to the locker room all too eagerly, his mind filled with imagination of isagi eating his ever so precious kintsuba. As they enter, He eyes isagi as he approaches his locker. Isagi stills as his hand slowly reaches out and clutches the kintsuba, he looks around with wide doe eyes, surveying the room to whoever might’ve put it in his locker, confusion plastered on his face. Kaiser panics and snaps his head away from Isagi.
Kaiser smirks internally “Yoichi must be grateful, overjoyed even, it’s not everyday you receive your favorite food after all! How great of a boyfriend I am… yoichi won the lottery with me.”
Isagi turns around and voices his confusion, “has anyone left their food in my locker? Kaiser…? Anyone…?”
Kaiser turns to look at Isagi and shakes his head in response. Kaiser follows Isagi’s line of sight, his head turning along with isagi. With a narrowed glare towards his teammates, as if to show warning to whoever dares to step up and claim that it was them who left the kintsuba.
The room is filled with choruses of denial and a shy smile lights up Isagi’s face and nods in return.
“I’ll… I’ll eat it then!” An excited smile is seen on isagi's face as he opens the box of kintsuba and stuffs his mouth full with it, both his cheeks adorably filling up the way a mouse would when eating food.
“M-Mäuschen…?” Kaiser thinks to himself as he watches Isagi eat with glee. Kaiser sees an image of a mouse happily eating away beside isagi and feels the urge to walk over and pinch Isagi’s cheeks and stuff him full with all the world’s kintsuba.
Kaiser abruptly leaves the room before he does anything to isagi’s adorable face, staggering by the wall as he clutches his hand, resisting the urge to walk right back in and squeeze the life out of Isagi, to nibble and bite on his cute and plump cheeks. “Is this… what cuteness aggression feels like…? Yoichi… yoichi should not be this cute…”

Kaiser now has developed the routine to pass by the convenience store and buy a pack of kintsuba every Sunday to give to a certain someone in hopes of seeing an adorable view once again.
