Can you write a scenario with Uta and his girlfriend when she lying him that she went out with friend, but actually she was in a coffeshop with a boy. But this “boy” was actually Uta, who changed his face, so he could test her. (sorry for my bad english)

Your English is good!

Uta smiles from beneath the face kagune that definitely isn’t him. He smiles because if he doesn’t, he’ll scream enough to split in two.

His girlfriend, the lover he’s told things he hasn’t even told Yomo and Itori, is cheating on him. She told him she was meeting a friend, but she’s actually meeting a boy. Only the boy is him this time.

He leans in closer, his fingers moving to her arm. She frowns and stands abruptly. “I think we’re done here.”

Uta watches her saunter out of the shop, feeling empty inside. Maybe he’ll just stop taking her calls. Maybe that will be troll-like enough for vengeance. 

He knows he should laugh it off, but he can’t just yet. 

But he’s hardly expecting her to be standing outside his home. 

“And here I thought you were out with a friend,” he says, feigning surprise.

“And here I thought you were at work.” She grins, all sweet and sugary, like the way she drinks her coffee, like she isn’t cheating on him.

“But I guess you were still mask-making anyways,” she murmurs in his ear.

“Huh?” For once in his life, Uta is stunned.

“Ha!” She steps back, laughing with abandon. “I knew it!”

“You knew that was me?” he demands.

“Hon,” she says, in that tone he adores, “I’ve been trying to get you to confess your identity as No-Face for months. So I took drastic measures, told a few lies to scare you, got you suspicious enough to ask me out under another face, and boom! there you are.” 

“You’re kidding.” Uta is impressed. And relieved. Like, so relieved he could cry.

“I’m not – pretty smart for a human, eh?” She pokes his nose. “I want you to trust me enough to know your identity. Honesty is so much easier.”

“I’m No-Face,” he says quickly. His head spins. 

“I know. But you’re also Uta.” She kisses his lips, tugging him into his apartment. “And there’s a few things I only do with Uta.”
