Question for the Bl readers

What is a Bl that changed something for you or impacted you?
Mine was “darkness before the dawn”, after reading it, I could not get into any bls that had no plot or a terrible art style. Weeks after reading it I went to read some popular manwhas that people had said made them cry, and it didn’t evoke emotions from me like this one did, just my opinion.
But I want to know if this had happened to you, and if so what did it.
