Like "Half of Me", " HSRoaG" also includes a body-switch plot. A mafia member tries to save a high school student who is about to kill himself, but he ends up dying instead. In this story, the gangster stays in the high schooler’s body 24/7, but he occasionally sees and communicates with the boy’s soul. Since he was a gang leader, he can’t help acting tough and intimidating, which makes the series even better and funnier. HSRoaG was originally a bl novel but because that mafia was originally around fifty-ish years old, they changed the adaptation into a bromance.
They basically have the same plot, apart from the mafia part. The protagonists also fall in love during tutoring sessions in Dangerus Romance. I personally didn't notice the similarity 'till I see the mechanics part, though.
