Bro I kinda get where Luca's coming from the reason why Luca doesn't like his uncle is becaus
Spoiler!
In the past life the uncle didn't die for Luca because he loved him it was becuse out of duty and guilt. If that happened to me of course I wouldn't want my family to go through the same experience i had . He only doing this to protect his aunt from being heartbroken later on .
I love bl action killing and manhwas
