I have my birthday today (i am 20 now) and thought maybe you could come up with some birthday party headcanons with birthday!reader x Uta, and maybe the Clowns? :3 just if you want of course

Happy Birthday Nonny-Mouse!

– from the moment Uta found out your birthday, he has been planning this party. And your mask. You may be a human, but he knows you like his masks. 

– Itori and Roma were hired to take you out in the morning. Roma insisted you needed a new birthday outfit. Itori insisted it be sexy.

– Nico showed up halfway through your shopping trip, after “sleeping late.” She actually was in charge of helping Uta sneak all the wine, blood wine, coffee, and cake from Helter Skelter to HySy.

– Souta begged Uta to let him sneak a finger in the wine to freak you out. Uta considered it, but refused. He then plied Souta with his entire eyeball stash so he would help him decorate.

– Donato does not help set-up, but he agrees to make an appearance. 

– Yomo does not want to be in the same room as Donato, but for Uta and you, he too will appear. You make Uta happy, and that’s enough for him.

– When you arrive back at HySy, the Clowns + Yomo yell SURPRISE. 

– Donato makes a point to tell you he thinks you’re a good match for Uta, despite your humanity. You take it as a compliment, which endears you to him.

– You are surprised how good the cake is. Souta then tries it, remembering the days he too could eat cake.

– Souta feels ill, but refuses to vomit it up. So Itori forces him to drink blood wine until he does. He is, however, now quite drunk.

– Nico, also drunk, tries to seduce Souta. You intervene, and Donato gives Nico a sermon.

– Souta then begins tickling you. He demands to know if you love Uta. You say yes with a red face. Uta can’t help but smile.

– Souta then asks if he can arrest you for harboring ghouls. “You’ll have to escape,” he says, “and wear a disguise.” 

– He presents you with a mustache and PARTY glasses. “Your disguise.” 

– Yomo begins gushing about how much Uta has blossomed in your presence and how he can’t imagine anyone better.

– Itori and Roma begin comparing boobs. That’s when Uta decides the party is over.

– When the guests have been escorted home, Uta gives you your mask. “Thank you for being the best part of my life,” he says, sealing your love with a passionate kiss.
