He didn't love Dr. Ai, until the very his heart is still for Adolph Airob
I do think he did love him but he spent his 10 yrs of his life loving Adolph, I think it's a love that's hard to move on from(I bet if he had more years to move on, he may actually 100% love Dr. Ai)
Does lewis really loved dr. Ai? Or.... Something....
