I am aiming to build muscle and I don't wanna count calories?

Then don't count calories. Watch the scale. Watch the mirror. Adjust your diet accordingly.

if you are lean and you want to build muscle just make sure youre eating 3 meals a day and you are eating a lot of carbs which include rice, bread, potato etc. also when you do weights, do low reps high weights and do them fast eg. when doing the bench push up fast and pull down slow. good luck

You leave a lot of information out such as your current height, weight, and age. Are you expecting to have a bodybuilder type body? Then you're going to have to diet. Or do you just want to be strong like a powerlifter? In which case you can pretty much eat what you want?
