>>914723Rookies is kinda like that, but it's more he's super friendly and wants them to succeed in life and shit and when they fuck up/don't listen to him he gets angry, but he's mostly being serious with a joking personality but when shit becomes rough he becomes serious and tries to make things right.
Also I imagine some of the works of FKMT might be something you'd enjoy, While it's mainly gambling or people leading a depressing life there is usually some form of someone telling the protag they're a sack of shit and have an awful life and it's THEIR FAULT unless they fucking fix it.
