it’s still ongoing at 87 current chapters and is rather smut heavy at first (rest assured no SA or anything gross like that thank god, they’re just two guys who fully match each others freak.)

but.. by the latest chapter the story is ‘very’ sweet and quite surprisingly heartfelt.
I don’t want to spoil it but I’ll just give you the heads up to skip the anime adaption if you decide on doing so for the sole reason on how fast it jumps right to the porn, I’m not kidding.
it also got a live action drama adaptation if you’re into those with 10 episodes if my memory is correct.

I want to read some good Bl, with good art, good redemption arc. Where one of them is so down for the other, but it also has a chasing arc?
