Imagine this with your OTP.

Person A and B are taking a walk to/from a mission. They are walking in silence. The only noise is the sound of rush hour traffic and a person playing a guitar, hoping for tips.
The preformer starts to play Person A's favorite love song. Person A looks at Person B and grins. They look amazing, like always. Person A can't hold back any more. They take Person B's hand and twirls them, catching Person B off guard.
"What are you doing?" Person B asks.
Person A releases Person B's hand and bows/curtys.
"May I have this dance?" Person A asks.
Person B blushes, but nods. They take Person A's hand and dance.
Neither of them are perfect at it, but they don't care. They gaze into each other's eyes and zone out the people who have stopped to watch.
The song stops and it starts to rain. People run to find cover, but they keep dancing.
They dance for what seems like forever. Soon enough, they are drenched.
Person A looks at Person B, their hair dripping with the rain. They laugh and kiss Person B on the cheek.
Person B shakes their head.
"You missed." they say and kiss Person A on the lips.
