He doesn’t know how to show it
Spoiler:
His father(the previous emperor) neglected him so he thought that that’s how a family should be he doesn’t know that u have to pay attention to ur child or spend time with them, that’s why he questions/ gets confused when FL tells him to spend more time with his daughter
honestly its super understandable why the ML doesnt really like nor trust the FL but he's an asshole for basically neglecting his daughter. he's not so bad overall though
