(Just going by the theory!!!) 

"WHAT THE ACTUAL FUCK!? YOU'RE SUCH AN IDIOT! WHAT TYPE OF FUCKING VERSE WAS THAT?!?" Tomura rages with a tomato red face, smacking twice. "You know you wanna fuck her though!" "NO I FUCKING DON'T" They argue. "Guys! let's just make the darn cake already~!" Toga pushes the two apart. "but I'm...not good at baking..." Tomura sits by the table. "That's fine...we can make the cake and you can decorate, fair?" Toga takes out a bowl and whisk. "Yeah...I guess..." Tomura says sighing.

[Y/n's POV]

"Where're we going?" I ask trying to catch up to his large strides. "you'll remember when you see it..." He responds a little nicer than usual. "Mm....alright.." I look around at the quite neighborhood we were passing by. "wait....don't tell me..." I stop as we near a familiar looking house. "What's the problem?" He asks stopping and turning to look at me. "I...I'm not welcome in that house...." "I'm not either, but here we are...." He smirks and goes up to the door. I don't budge, just watch him knock on the door. I see the door open but don't see who opens it, due to Toya's large build. "Who are you..?" I hear a very much missed, familiar, male voice. "Get your sister and brother...." Toya says calmly. Though I can't see his face, I know he knows what he's doing, yet I still fear of what they'll think of us.

[Dabi's POV]

"Alright..." Shouto says before calling our other siblings. "Yes-" Fuyumi asks than when she sees my face, she freezes. "Who....Toya..?" She asks stepping forwards cupping either side of my face. "Yeah...it's me.." I say deeply. She presses her lips together tightly and hugs me. "Where'd you go..?" She sniffles. "Somewhere, where no one takes my freedom away from me...and she did the same...." Once she lets go, she gives a confused expression. I step aside to reveal Y/n. Fuyumi's eyes widen as she stares at Y/n's figure. "Y-Y/n..you came back too...?" She asked quietly stepping forward. 

[Y/n's POV]

I look at my older sisters light grey eyes, as they dwell with tears. "Y-Y/n you came back too...." She takes a step towards me. I was speechless, how could she have missed me? She than runs back inside and grabs Natsuo. When he saw me, his signature smile started to peek through, he looked like a train wreck though. "Y/n?" Shouto than peeked out the door and his eyes widened. 'Shit..' I step back and tilt my head down, trying to avoid eye contact with either of them. "Y-Y/n....you're back...." Shouto says than sprints towards me and pulls me into a tight hug. "S-Sho...." My eyes start watering. "We've missed you so much~" Fuyumi breaks into tears and Natsuo hugs Toya. 

"Happy birthday sis..." Toya smiles. "how'd you know that I wanted this?" I wipe my tears. "I always know what you want..." He smiles pulling back from Natsuo's hug. "of course you do..." I chuckle while Sho pulls back. "but....I shouldn't be here.." "what do you mean?" Sho asks. "If i stay here any longer memories will come back to me and i'd hurt you guys.." I step back and start running towards the city. Sho looks back at our siblings and sighs. "just let her think..." Fuyumi says walking back into the house. 

'No...I can't be there...' I keep running unaware of all the people staring at me. "oh no...i'm not wearing my mask!" My face goes pale. I look at everyone and notice them going back to their usual shit. 'I guess they thought the league got destroyed...hopefully, cause if i get caught i'm in big trouble...' I think nearing a park. I take a seat at the bench and cover my face with my hands and groan. 

-Meanwhile-

"What do you think Y/n would want?" Toga asks. They were currently at the supermarket looking for gifts. "I don't know....maybe these~?" Twice holds up a box of condoms to Tomura. Tomura blushed and put his hood over his head. "I already said she probably doesn't want to do it with me....so cut it out!" He stuffs his hands in his pocket and pouts. "Yeah....probably" Twice smirks. "will you two stop being boys for one second and actually help me?!" Toga says pulling them to another section of the store. 

"Well damn....I thought you were gonna help with the match making..." Twice frowns. "I already have a idea or two~" Toga grins. "you guys go get decorations and i'll handle getting the other things." She hands the guys a list of decorations for the party and than pushes them towards the party section. "I guess we don't have a choice then..." Tomura starts looking for the things. 

-With Y/N-

After a while of resting my eyes, I look up to see a little boy standing in front of me. "Can I help you..?" I asked sitting up. He crawls into my lap and snuggles against me. "The fuck!?" I panic. "get off of me!" I attempt to shove him away but he's holding my waist tightly. I stand up and still try. "I said-" He looks up at me and smiles. "I've been looking for you everywhere mommy~" 

"Wait....Mommy?"
