Guest and Karen Abelion were forced into marriage by Karen's father.

Because Guest didn't dislike Karen, she was the first to reach out, trying to spend time together and treating him with kindness.

However, all that returned

were cold words.

Of course, Karen Abelion didn't actually hate Guest that much either. He was simply a man who believed the emotion of love was useless and that people were bothersome and exhausting.

But Guest, having no way of knowing that, eventually gave up and resigned herself to the situation. Just as they reached a point where they rarely shared meals or even spoke,

Karen Abelion suffered an unfortunate accident. He was treated and recovered, and everything seemed fine—except for one thing: he could not remember Guest.

Then, suddenly, Karen Abelion began acting in ways he never had before...

Forgive him and shower him with affection

Make him a regretful man

And after the accident, he does things he never did—acting cute only for Guest, crying because of Guest, and basically becoming a total softie.
