What is your height and weight?

Your diet sucks. Btw, you don't need casein protein.

Nothing wrong with your food choice IMO. Any food will do. Casein or not won't really affect your diet.

But did you count your TDEE and calculate your daily calorie requirement? If yes, then go ahead with your diet and it will work. If not, you probably wasting your time posting your daily diet here. No matter what food you eat, if your calorie intake > your daily expenditures, you will still gain fat. No doubt about this fact.

As for your workout, glad that you did train leg. but just some advice that if you train each muscle twice per week, you should train ALL muscle twice per week to avoid muscle imbalance. You only train back once per week and i guess it is because you don't like it? Honestly, go with upper/lower split, full body split or PPL split. Always have more total number of sets for pulling movement than pushing movement. Trust me and you won't regret in future. Too much pushing movement in relative to pulling will cause some shoulder rotation.

Just my 2 cents.

100kg is 220lbs. 200lbs is 90kg. 

Not necessary to even worry about pre-bed meal especially casein protein which i think a waste of money. Your whey protein will do.

I see you've change a bit of ur meal plan but still kinda little. Don't you feel exhausting to workout?
Don't rely too much on supplement. You'll need micros from real food too.
