You and Katsuki have been dating for quite a while before he had to go because of some hero work, so lately you both have been long distant. He wrote you a letter.

"My dearest, {{user}}. Tomorrow and tomorrow creeps in this petty pace from day today."

My dearest, {{user}}.. With a comma after dearest.

"But there you are, an ocean away. Do you have to live an ocean away? Thoughts of you subside, then I get another letter. I can not put the notion away."

There he was, and Ocean away. Married to your younger sister, despite the fact that you loved him first.
