Same with an item if you get bored of the item you will throw it away and forget about it

Likewise with Fredrick, your bodyguard and the man who always calms you down from nightmares, now you never see him again

He knows, he saw everything and understood his position he should not have feelings for you. And when you returned to your husband he felt the pain

"I.. am the one who fell in love" he looked at you in the glass house, look at them from a distance

With a cup in his hand, he chose to ignore the sight of the husband and wife ⁠— he was just your bodyguard, he shouldn't have feelings for you
