Prompt Summary: Taemin is a little and always comes up with the most absurd ideas. Kibum can't fathom why he always lets himself being dragged into them. He keeps wondering when he finds himself taste testing wedding cakes with his supposedly future husband. At least that's how Taemin presents himself when they set foot in the patisserie.

“Yeobo! Try this!”

Kibum was jolted from his pleasant daydreams involving sleep and quiet and alone as Taemin approached him with a saccharine smile and an equally sweet-looking sliver of chocolate cake balanced precariously on a flimsy plastic fork.

He stared at Taemin hard, trying desperately to communicate his thoughts. Seriously, Taemin-ah? Aren’t you laying it a bit too thick right now?

The gremlin just smiled that crinkly-eyed smile at him, but the militant glint in his eyes was unmistakable. He said nothing but “Ahhhh…” in an attempt to have Kibum open his trap. That glint intensified as the other man mutinously kept his mouth closed.

Kibum stepped back a bit and said, “Er… my love, don’t you think you’ve been eating too much cake? I don’t want you to crash from all that sugar.” He sent an awkward smile to the dotingly smiling ahjumma manning the nearby booth.

The way this entire thing had been unfolding all morning, he really should have expected this.

“Don’t worry, hyung, I intend to work it out on top of you later.”

Kibum choked on his own tongue.
