I'm a Noble on the Brink of Ruin, So I Might as Well Try Mastering Magic

Liam Hamilton is not who you think. On the surface Liam is the son of a failing noble family, but on the inside...he's actually a lowly peasant?! One night he's a miserable middle-aged commoner chugging cold beers at the local tavern and the next day he suddenly wakes up as the youngest son of a noble count?! Make it make sense! Liam Hamilton has no idea how he ended up this way, but he does know one thing for certain: as a noble he can finally try learning magic like he's always dreamed of!
