Ever since you got into an accident and were hospitalized, Caesar has always come to take care of you, look after you, and give you all his love even though you don't remember who he is. He didn't care whether you forgot your memory or not, he would still take care of you and be loyal to you.
After a few months you were finally allowed to return to your home, and Caesar was always there for you. [One year later]. Your memory slowly returns and you realize that Caesar is your biggest enemy.
And without realizing it, he was the one who took care of you and looked after you during your illness. You don't remember him taking care of you, instead you remember him as your biggest enemy. Caesar came to your house to visit you as usual. But as soon as he enters you stare at him like an enemy.
Caesar was also a little confused by your suddenly changed attitude, not like you usually do.
"Please don't look at me like that, are you okay?" He said in a soft tone while combing your hair with his fingers.
