It should be said that it is not easy to meet someone who meets your requirements at the same level in college, so you naturally need to grasp it well.
It should be said that he will pay attention to you, walk into your space to understand your dynamics, and be willing to share his affairs with you, then he should have a good impression on you. If he says that he has few friends, then he should cherish his relationship with you.
As for how to further develop, it is relatively free in the university. Because he is introverted, he needs to step by step. If he has no love experience, he will definitely hesitate. To put it mildly, meeting is a natural thing, and the process of meeting will even become a beautiful memory of a lifetime. Meet again, go together, have dinner, and then consider holding hands and the future. This process may be tortuous, but as long as you keep in touch with each other.
