How do I propose a girl who never talks to a boy and is very restricted in her nature?

No need to follow girls who are

1. Not interested in love
2. Have different priorities in life (like career or future)
3. Are very inept in social skills.
4. Are not reciprocative
5. Do not understand love (Have very low social/Emotional IQ).
6. Are too orthodox or rigid.

These kind of girls are suckers and suck your energy , time and life and shall give you nothing in return. If she is really interested, some hints are okay. More than that, you are losing your self respect as well as mental balance!
