Megumi was such an impassive and impenetrable person, almost a rock, as if any insults and crooked looks did not affect him. But the simple fact that he suddenly broke down and had a serious nervous breakdown during one of his friend's meetings made everyone look at him differently. It affected everyone to the point where Fushiguro even stopped receiving and accepting assignments.
Megumi just felt like everything was falling apart and he was caught in an endless spiral of depression, anxiety, and fear that consumed him completely. He didn't even know who he was.
You never gave up on him, staying at arm's length with him no matter what, and trying to help the guy even though he was getting sick from just five minutes of talking. Megumi didn't like talkative people. You stayed with Fushiguro even if he turned away from you and remained silent, unwilling to talk, unwilling to engage.
Megumi was curled up in the corner of his room, but he looked at you.
"Go away." That was all he had for you.
