Can it really be called infidelity or cheating when they were meant to be together from the start? Notice that Erwin married his wife because she took a liking to him and is the daughter of one of the investors or someone rich in the company. So, Erwin and Levi just return to how they were before. Note: I personally hate cheating and the likes, but considering they always were meant to be, it doesn't feel like they were cheating.

Ok, ok. I have to confess, I never liked The pairing of Erwin x Levi that much, Maybe because I like Levi as a seme more that an uke and cuz Levi x Eren is more my type. But in this, I don't know what is, but Erwin looks so manly! I don't know why, but that's The impression I have in this story! Probably because he was so caring to Levi and he help him with The breastmilk overflow. I was in The same as Levi and to be helped that way is so romantic. I love You Erwin!
