I'm actually not sure if it's a bl but it's like those transmigration type of bls where the mc transmigrates to the body of a young boy who has connections to the ml (they met in a forest.) and that the mc spend a lot of time leveling up or getting stronger (I forgot for what purpose though.) though the mc wasn't aware he actually met the ml until at some point in the story. It's been years since I read this, so it should be completed by now ..
