Izuku gets invited to the Shadow Daddy Club

If you read fantasy romance you're probably familiar with the term "Shadow Daddy" (see ACOTAR, Fourth Wing, etc). A Shadow Daddy is a MMC who, in one way or another, has the power to weld shadows or darkness. He's usually the tall, dark, handsome villain who is actually secretly the good guy - a point that is usually revealed in fantastic enemies-to-lovers fashion. He is always dangerous, the dirtiest/scariest/best fighter, and mind-blowing in bed. He always gets the girl.

Enter Izuku Midoriya. Sweet, sincere, innocent Deku, who cant speak to a girl without turning beet red and tripping over his own feet. Who has never even held a girl's hand, much less kissed one. The day after he gets his shadow quirk, he also gets an anonymous invitation in the mail to a members-only secret society called the "Shadow Daddy Support Group".

The prompt is for either

  1. a story told through the bewildered, clueless, and sometimes jealous POVs of the male population of class 1A, as they witness an awkward Midoriya turn into the most in-demand ladies man in UA history.

or

  1. Midoriya's POV as he discovers this secret club, meets and interacts with (unknown to him) infamous shadow daddies in fantasy romance, is taken under their wing, and finally gets the courage (and moves) to get the girl.
