It was actually pretty easy to stop liking it, cus I started reading like Isekai romance and like some villianess ones cus they mad interesting
I use to be a hardcore BL fan believe it or not, but not anymore, I'm mainly just into action/reincarnation manwha's.. So no, once you read BL, you CAN go back, and honestly I'm quite happy not reading it as much anymore, it was a very unhealthy obsession of mines
