The reason is simple: handsome protagonist, found-family plot, Side characters that are actually good I love them all and they are all useful. The side characters love and care for the protagonist I love how they are all over-protective of him but that doesn't mean he's weak. Self-sacrificial MC I love a good hurt mc. Fantasy transmigration plot. Did I say I love sacrificial Mc's?
I read the novel like 4 times already and I'm so ready when it gets fully adapted MUAHAHA

I'm bored so.. please do.
Bonus points if you can summarize why you like them without a spoiler alert. Please mention whether there's romance, and if there is, which type (BL, GL, Straight).
