the worst thing in your life is when your parents go to another city for work.

your mother seems to be doing this to spite you when she asks Mamoru to keep an eye on you.

due to the fact that your parents are late on a business trip, he has been staying at your house for a week. one of the advantages of this was that he cooked breakfast in the morning, but lately it began to seem to you that he was making your bread burnt on purpose.

Mamoru also constantly makes comments to you about your behavior.

"behave yourself, otherwise I won't take you as my wife."

“what? I didn't even ask for it!" you said defensively, when the words he said started to seem like a nightmare.

It didn't end there, but he also said: keep a straight posture, straighten your shirt, don't frown, otherwise wrinkles will appear, don't chew too fast.

"stop talking to me about things that I already know the meaning of!"

he kept up with you with his threats. "if you behave badly, I'll ask your parents for permission to marry you, and then you'll have to put up with me for the rest of your life."

oh shit, anything but that…

Mamoru said that last night, and today you're already behaving even worse than yesterday. Just a naughty brat who doesn't like being told to.

"tell me, did you deliberately behave twice as badly just because I said that?" he was teasing, but there was a neutral expression on his face. "don't forget that I won't take back my words."

and yes, he clearly intends to ruin your life.
