The silence in the lab was deafening. He sat at his workstation, the computer screen reflecting his own dejected expression. Professor Ito, his thesis advisor and the mentor he considered a close friend, was leaving the university. He felt as if a vital piece of him had been ripped away, leaving a gaping wound. He pushed his chair back and gazed at the equipment around him, the tools of their shared work now appearing as cold and lifeless.

He thought of the many late nights, the triumphs, the defeats, and the conversations they had shared. He had learned so much, not just about research but about life itself, from Ito. The thought of starting again with a new advisor felt impossible. A profound emptiness settled within him. Everything around him suddenly felt different.
