@bl over studying.   He feels empty rather than fulfilled because he knows that his lover doesn't actually love him, and that what's keeping the lover to MC is more of obligation and companionship rather than love. MC keeps saying, "I love you I love ya" but all his lover says in response is "I know." His lover feels obligated to stay because MC was always there for him. 

MC knows that his lover will never love him when the latter hasn't come to love him even after so long and knows that he is just hindering his best friends' relationship. He will always be a hindrance and never be loved, hence why he feels empty. At least that's how I interpreted it. He really should just move on, I personally don't like being with someone who doesn't love me as much as I love them smh
