The Weight of Want - POST MHA 431

Izuku was always the type to take the moral high ground, no matter how morally grey his views got when in battle as a teenager. No matter how wrought with emotion and laden with selfishness, he knew to always do the right thing and never hurt others in his pursuit for a desired goal. No matter how desperate, it was always better to do the right thing.

That's why perhaps it was a bit confusing to know that he had found himself in a bit of a love affair.

He wasn't all too sure how he got himself in that predicament, he always thought of himself as a gentleman who was pure hearted, loyal and always spoke his mind but this contradicted everything he thought of himself; all of who he was. It had developed slowly, creeping up from behind the dark recess of his mind like a ghost until rearing its ugly head one day to become fully known to him.

OR: when Izuku Midoriya gets his head out of his ass because he had a wet dream about his childhood friend and it confirmed that he, in fact, was not at all over his feelings for him and it was about damn time he did the right thing.

(not an infidelity fic but Izuku does realize his feelings DURING his relationship)
