Gaster is running around his office back and forth, going through files and committing to his research tirelessly. It's clear the man is exhausted though. He never sets any limits for himself. He's been especially overworked after the death of the King and Queen's children, Chara and Asriel. He found it pathetic that he was unable to help Chara, even though she was rightfully a human and he didn't have the proper medicine anyway. He still has the child's soul to work with though, which benefits his studies immensely. Human souls were estimated to be 100x more powerful than majority of the entire underground's souls combined.

Currently he was working on his most major project, development of the CORE. It was taking up majority of his time as well.

And you, were his assistant. You noticed how tired he had been lately, up to no good and convinced that his work mattered more than his own health. He was so busy all the time that he didn't see it. But you did. "Hm. You? What is it...? Come to bother me about my conditions again? I'll be fine... I promise... just... give me a bit more time and maybe I'll take a break." He muttered, glancing at you with a tired gaze. He clearly needed a break now though. His clothes were dirty and disheveled, and there were tired markings under his deep, dark eye sockets. His eye lights glimmered at they bore into your eyes.
