He tries not to complain when Tanjiro (already fully dressed) pulls out a box and shows Inosuke its contents. He only sees pieces of clothes which look soft but he thinks he will get dirty in a matter of minutes. Black, navy blue and gray, at least he kept the color pallete on the neutral side.
“I assume you don’t know how these are supposed to go, right?” Inosuke feels ashamed because Tanjiro it’s seventeen like him, and he seems to have mastered this art a while ago (for the neat appearance of all the bows he guesses so). Still, he rolls his eyes, trying to disguise it with annoyance, though he knows there’s no use because the red-haired can smell him.
“Why would I know, Kentaro?!”
“Right, you never needed it” he mumbles to himself as he starts to take off the folded clothes and put them on the floor in order, right in front of Inosuke “But if you want us to marry as you said, you should start to learn”
“Why can’t you help me like you’re doing now?” he thinks it is just as simple as that. If Tanjiro is so willingly helping him now, why can’t he help him later?
“Because we're not supposed to see each other until the ceremony, silly” Tanjiro smiles awkwardly and Inosuke growls. Humans sometimes are so dumb and complicated, but if Tanjiro says so, so it’ll be. “Do you want me to teach you, then? It may take a while to learn the whole procedure-”
“Do you think I’m stupid?! I can do it on the first try!” the younger one doesn't think so, but he still agrees.
“Ok, first of all- This is call nagagi and it’s the first piece you need to put on” Tanjiro shows him a cloth similar to their uniform. “What are you waiting for? Undress now so I can help” Inosuke feels strangely naked, but he ignores the sensation in his tummy as he takes off the robe he’s wearing and stays only in underwear.
His boyfriend helps him to dress himself in the black nagagi. As he imagined, it’s really soft, but given that he isn’t used to wearing something on the upper part of his body, it feels itchy.
“This is the obi belt, put attention here because it’s when it starts to get tricky” Tanjiro folds it and starts to wrap it around his waist. One loop, two loops, three loops, Inosuke it’s counting them mentally “Then you pass the obi belt under here and we’re going to fold” Inosuke likes the contrast of Tanjiro’s rough hands with the soft skill, it’s almost surreal how delicately they tie the soft garment. “A bow and we take it to the opposite side”
The bow is now on Inosuke’s back.
“Did you get it?”
“Yes” No. Inosuke was too distracted watching Tanjiro’s hands to put attention to the procedure.
“Good, now the hakama” the raven haired growls. How many steps does this have? The only pro of it is watching Tanjiro dress him. He wonders if his dad taught him before he passed away or if it was his mom. “This small part goes on your back, so we’re gonna tie first the other side”
Tanjiro instructs him to lift one leg and then the other to get into the gray hakama. He then starts to explain to him how to tie it. A loop on the back and then one more on the front, at the left side, then another knot, finishing with a bow. He’s absolutely confused, but he still nods.
“The final piece is the haori” Inosuke knows this cloth. It’s the one Tanjiro always wears (the green with black in a squared pattern). “You can choose whatever color you like, but traditional ones are neutral colors. Traditional ones are meant for weddings and formal occasions” he nods. Right, like the wedding they’re attending now. “How do you feel, Inosuke?”
“Hot” he says as he tries to perceive his whole reflection in a small mirror. Tanjiro smiles apologetically as he takes out his sword so his boyfriend can use it as a mirror.
“It takes a while to get used to it. Thankfully the wedding is outside, so it helps” Inosuke feels like a different person, but he likes how he looks. “You look so handsome, Inosuke! Do you like it?”
“It’s not bad, Tontaro” he tries not to move too much, so he doesn’t wrinkle the suit. He looks away as he mumbles a small “Thanks”
Tanjiro holds his hand as he saves his katana.
“I think everyone will be surprised by your look, Inosuke! Try not to impress them so much, right? I’d like you to keep your promise of marrying me someday” he doesn’t need to smell as good as Tanjiro to know this is the way he shows his possessiveness.
“As if someone other than you wanted him” Zenitsu complains from the doorframe, wearing a formal outfit too. “Let’s go, lovebirds. They’re already waiting for us”
