This is Kawaguchi Hidetoshi. This is my humble answer to the question.
Being called a “menhera” is troubling... it is truly a problem for my heartless friends around me.
If they are simply being criticized, I wonder if there is room for improvement by strongly denying it or clearly conveying what they dislike. Even so, if you still don't seem to quit, I think one way is that you can change the way you socialize if you're not a real friend rather than someone who can think about the other person.
That said, while relationships have already been established to a certain extent in the small, narrow world of campus life, I think there is some resistance to quitting friends or quitting relationships now.
So, to be honest, changing your personality may be difficult, but as I mentioned in my humble answers to the questions and answers below, I know that it is possible to change your personality for the better by changing the factors that are the causes and conditions of your current personality for the better.
For example, as Mr. Hasegawa has already mentioned, I think one way is to brighten it up from the outside. There are also many women's fashion magazines aimed at young people. So I think it's okay to do a little research on hairstyles, makeup, clothes, etc., and try it out.
It doesn't matter if you've already finished, but if you're going to be job hunting, I think it will also be useful for how to make a good impression in an interview.
Question “Can I change my personality?”

“... Of course, personality also has become your current personality due to various causes and conditions, but by thoroughly investigating and understanding the causes and conditions that are your current personality, you should naturally be able to change your personality for the better by changing those causes and conditions for the better. ・・”
I pray for good deeds.
