Goodbyes Are Always the Hardest by Gaia_Bing
When AI Nasir and android Agron are paired together for space-flight missions, they spend ten wonderful years together. Their friendship deepens and they learn to care very much for one another. However, when Agron retires, he is forced to let go of the one being in the galaxy that means the most.
This story is absolutely enchanting. Sometimes AI/android stories (in any genre) can come off sterile and cold, but this one is not like that at all! Your heart will melt and subsequently break as you watch these two beings develop feelings for each other and inevitably be forced to leave each other's sides. Please give this delightful story a try! It will warm your heart!
