just like the title, bl novels that I would 100% take it with me if I go to mars and don't die of boredom even if I already read it numerous times already, or you could just interpret it as “5 stars top fav omg best thing ever” okay maybe that's too much let's just say that it can't be okay fine decent good rating, it has to be “wow I enjoyed reading this so much I could totally see myself reading this and get extremely upset after finishing it.”
