If you want to know what happening that is Mc real father and the mc and real princess did not swap soul rather than that the real princess body is possess by the author of the book the our mc reading ( I think it is in between chapter 1 to 10 ). 

Bestfriend is more likely a brother or sister. They care for you and they are always straight forward example if your make up is ugly or if you wearing an old fashion clothes they say harsh things but they still care because they want you to look good also even they say that thing they will give  a clothes if don't have a good one and they will also fixinh your makeup. They even help you when someone else bullying you and always help each other in time of crisis or problem without expecting anything. Take note even you have some many friend they think it is a good things. Also if you get a good grades and have a good relationship they are proud for you they do not feel jealous. They support you in all good things but they will become you mother when you do a bad things.

Friend is like give and take. It is like a person you know or more like a group of people chatting about something else like trending, artist, model, and etc. They meet each other and they spend time on something fun together. They like "you treat me good so I treat you good too". Also sometimes friend also feel jealous when you get a good grades or good relationship and having a more friends but they know it has a limit.

Fake friend is the worst one they act like good but they stabbing your back. They always feel jealous in your grades so thats why they create a fake things about you and also if you have a beautiful or handsome partner they will create a misunderstanding so you and your partner will fight. They are snake or an angel outside but devil inside.

Take note any kind of friend will impact your life and you will remember them for the rest of your life.
"Friend is like a leave they have a kind; the fresh one and the rotten one but if you look for a true friend is a rare one as if you are looking for something unique or special leaves in the trees" So if you find you true friend greet them better.

Ang daming marites.
