I Regressed to My Ruined Family Light Novel

Description:

Ethan Ardan definitely remembers dying, so when he wakes up in a dreary room with his sister who’d died, he can only presume it’s the afterlife.
It turns out Ethan has been reborn into an alternate timeline where his relatives bankrupted his family and dragged it into disgrace while he was in a 10 year-long coma! Now,
it’s up to Ethan to use his powerful skills from his past life to reunite his family, and to make his relatives rue the day they started a fight with House Ardan!
