How to Rebel ?? Suffering from elder sibling syndrome !

21M finished my CA inter on 21st Jan, So I'm playing Valorant for last week, for atleast 5-6 hrs a day, cause I don't want to get addicted to any other NASHA cause I want chill and have lots of free time, but now Dad is like Chote Bhai ke 10th Boards hai, don't play at home, go anywhere else and Play.

When it was my Exam they I was told to Go to library of I'm feeling disturbed, Now I want my peace at home, still they can't bare me at home. Mind it I was studying atleast 14hrs a day.

Now he's taking my Laptop to keep in his Office Locker room, and now I want to REBEL so bad.

But can't Rebel cause afraid if it will hurt my parents

Suggest how to Rebel, or how to chill without lossing attention retention .
