What's Her Quirk?!

Singing Together

We both laugh as we sit on the couch and he pulls me into his lap, "You really like that choker I gave you."
"It's my favorite, it was the first gift you ever gave me," I say and kiss his cheek.
Katsuki holds me close to him then suddenly holds his cheek, "Ow!"
I get worried, "Are you okay?"
"You're giving me a toothache by being so sweet, stop it," he says, smiling.
I roll my eyes and mess with his already messy hair, "Your pickup lines are so cheesy but so very cute too," I say and kiss his cheek, "I'll never stop being sweet."
He leans in and kisses me deeply for a minute before pulling away, "So, you know any duets?"
I smile widely and giggle a bit.
"I'm not sure whether to be excited or worried," he says.
I start humming a song that's familiar to him then he starts to sing as I get up and pull him up with me, making him dance with me as we both sing.
"Don't go breaking my heart."
"I couldn't if I tried."
"Honey if I get restless."
"Baby you're not that kind."
He spins me a little and we dance to the music in our heads, soon laughing them off as I trip and fall, bringing him down on top of me. He calls me clumsy and I can't argue with him since I did trip, plus I was laughing too much to say anything. We were just silly with each other and had fun, putting on actual music from his phone after our throats started getting sore.
