[BKDK] Our Fatal Love

With a drunk act, Izuku is believed to have had a one-night stand with a married man, and in desperation, he gets rid of the ring to set his mind in peace to focus on his studies and forget about the man. But what seemed to be just some random one-night stand gets him tied up with many things he would never have suspected to come from it.

Or Izuku gets drunk and forgets he had married a man who has..a side business that the man's family runs..
