Having two bunnies that live together isn’t a lot more work than having one, but having two bunnies that live separately is quite a lot more work. You would need to keep them separately for at least the first month, then spend at least a month bonding them, so it’s a big commitment. It can also get expensive if you have emergency medical bills for two rabbits. Both bunnies need to be spayed and neutered before you can bond them.
You’re right that bunnies do need a lot of companionship. They’re social animals and they do get lonely if they don’t receive a lot of attention. If you’re spending less than two hours a day with him, 5 days a week, it means that he’s alone for 22 hours of the day, which isn’t really fair on him. Could you perhaps move him to your bedroom, so he could at least see you when you’re sleeping etc? Perhaps you could also get a set up at your dads house, and bring him with you if he’s a calm rabbit that doesn’t mind travelling.
