This story seems to have started many other BLs this year with this horrible plot of the brothers, although I'm not a fan of addict heroin or the only one, but you can still watch it because they didn't grow up together, but this one, the oldest one, was a father figure and a brother, even though they're not blood relatives, I believe that in modern families this is the least important thing unless one needs a blood transfusion, it's for those with a strong stomach, I felt uncomfortable, it's not the kind of story that I like, I think brothers have other types of feelings.
