The clothes Rein picked out for him each day were just according to his tastes but now that things had changed, he was beginning to realize its significance in his daily life.
Butler Bosch was left in charge of laying out the clothes he would wear after his morning routine but the old man's choices made him sincerely miss Rein's presence.
The Butler's actions proved to him that only Rein knew his preferences the best.
The clothes his chamberlain had placed out every single day were just according to his tastes, they were comfortable yet succeeded to make him look his best.
While Butler Bosch's choices were also impeccable, fit for someone of the King's status to wear, they were uncomfortable and troublesome for him to wear and move about throughout the day.
Therefore, he could not deny that he sincerely felt Rein's absence when he looked at the clothes that Butler Bosch had picked up for him for the last two days.
