It is normal for single men and women to kiss in love. Not too much. Parents' opposition is also good for you. College students have a high rate of breaking up in love. After graduation, they will go their separate ways and generally will not be together, which is one of the reasons why parents are worried. Remind you that you can fall in love, but girls should not give their most precious things to each other, lest they regret it later. You understand what I said!
I wish you a happy life and successful studies.
