What influence does puppy love at the same table have on me?

First of all, don't persuade him about puppy love. Her love is her business.

If she really interferes with your class, you can talk to your parents and ask them to talk to the teacher. You can tell your parents the truth, but don't let them tell the teacher that someone else is in love. You can find another reason to move your seat. As for what reason to find, let your parents bother, they have a lot of ideas in this regard.
