Sometimes, Shisui worries about Itachi's health. He's very small, see. Shisui loves eating large and balanced meals and eats three times a day with two snacks somewhere along. Itachi's eating schedule is a mess and he also ends up eating meals Shisui doesn't understand, like rice balls with seaweed. Where is the protein, Shisui would ask. Itachi doesn't really care. Shisui suspects Itachi just isn't interested in eating food. But he loves to cook and is actually amazing at it. More than once, Shisui has come home from the gym to find a beautiful complete meal waiting for him. He would kiss Itachi on the cheek then, thank him and eat with pure bliss. Itachi would join him, but more often than not Shisui would have to remind him to finish up, because he would find Itachi staring in the distance, chopsticks hanging lopsidedly from his hand, lost in thought.

Sweets are, however, Itachi's bread and butter. He can eat copious amounts of it. So Shisui always makes sure they have stuff at home because he knows Itachi will snack on them throughout the day. When Itachi goes to the gym, Shisui always sneaks in a chocolate protein bar into his gym bag. Itachi loves them and always eats it, even before the workout if he finds it then. This is Shisui's way of taking care of his absolute favourite person, to make sure he keeps a few extra pounds on him. Itachi never contemplates where all the goodies come from. They're a constant in his life, as is Shisui.
