The concept is my cup of tea. Doctor isekaid into a world where he’s amazing at his job? Great! Him regressing into a body of a 16 year old? And being paired with men in their mid 30s? Hell nah
Seriously, they could’ve atleast maintained mc’s body and it WONT even change the major plot at all. And yet somehow they turned him into a kid with a mind of a 40 year old just because??
