There are several possibilities. One possibility is that you are not as indifferent to these ugly boys as other girls. They are very polite and gentle, so they are attracted. They think you like him.

Another possibility is that you are also a creature with good academic performance. They think you are the same as them, and you don't necessarily care about your appearance.

The third is your idea, you are really this type of girl.

These possibilities can only be roughly inferred, because it is not easy to judge until I see them.
