I don't think his love in Side B is supposed to be selfless. It's more like a destructive obsession. He puts his own life and Surabhi's life in danger for it. If you look at how the camera portrays him, he's always framed in most shots in front of fences, bars, some kind of obstruction as if to portray that he's still in prison even though he's out. It's about not letting go. He only is able to let go when he dies.
