Heart was happy that Soul was working on his birthday, though he noticed that Mind hasnt been around, usually he'd hear his modulator picking up on his breathing, or his heavy footsteps.. but he hasnt heard of him. He thought that he should not worry since- Mind has always proven himself to be more capable than him in more ways than one.. but its his birthday.. and he had spent weeks trying to make him something despite his own blindness, he sighs then tapping around with his cane trying to mental map their house. He knew a few places that Mind would always be in, other than Mind's own room though he still checked.
