When Shouto has a nightmare
Shouto: *knocks on Deku’s door*
Deku: *sitting at his desk, looking over class/hero notes* “Shouto...?”
Shouto: *enters with a gloomy expression*
Deku: “...Another nightmare?”
Shouto: *nods*
Deku: *closes his book/journal, walks over to his bed and sits down on it, outstretching his arms* “Come here.”
*they just cuddle and talk about random things until they fall asleep. <3*

Trying to say the others given name for the first time - Deku
Deku: “Sh… Shou… ARE YOU SURE IT’S OK IF I CALL YOU THAT?!”
Shouto: “Yes we’ve been dating for weeks it’s fine--”
Deku: “SHOUCHAN!”
Shouto: “...Sh-Shouchan?”
Deku: “AH I’M, I’M SORRY! I’M JUST, I-IT JUST--”
Shouto: “I like it.”
Deku: “...Really??”
Shouto: “Yes. Shouchan it is.”

Trying to say the others given name for the first time - Shouto
Shouto: “Izuku.”
Deku: “...how does that come so easily to you?!"
Shouto: “I practiced.”

Listing what they like about each other
Shouto: “Is ‘everything’ an acceptable answer? Because he’s perfect.”
Deku: “Ah, w-well there’s no way I can list every single thing I love about him! That’d take years! I do like how soft his hair is, though. And how pretty he looks when he smiles. And how defined his muscles are. And--” *goes on for years*

Encouragement when the other is (badly) injured
Shouto: “Izuku, you’ll be fine, don't worry, I’ve got you…”
Deku: *probably sobbing* “Shouto, it’s ok, you're ok! It’ll be ok! Everything will be ok! I promise!”

How they celebrate their anniversary
Deku: *buys a bunch of gifts, plans them a full special dinner at some fancy restaurant, starts pampering Shouto from the moment he wakes up in the morning, just generally overdoes everything in a charming way,* “Happy Anniversary!!!!!!”
Shouto: *buys a simple, expensive piece of jewelry, cooks any and every food Izuku wants as best as he can, gives all the time, love, care, and appreciation he can offer,* “Happy Anniversary.”

Suggesting Marriage
*right after fighting a villain or some sht*
Deku: “Hey, Shouchan…”
Shouto: “Hm?”
Deku: “Have you ever thought about getting married?”
Shouto: “Of course I fucking have, let’s get married.”

Their future/Welcoming the other  home - Shouto
Deku: *comes inside, unannounced*
Deku: *finds wherever tf Shouto is*
Deku: *hugs Shouto from behind* “I’m home.”
Shouto: *smiles* “Welcome home.”
Their future/Welcoming the other  home - Deku
Shouto: “Home.”
Deku: *very tight hug* “Welcome back, Shouchan. I missed you.” *kissu*
Shouto: “I know. You were spamming me with “i miss you” and “i love you” messages all day.”
Deku: “I need to make sure you know. All the time.”
Shouto: “Pfft.”
