As soon as they joined the Institute they formed a “pair” with a male student, preferably from the same course. You can call the relationship as boy friend in terms of the present day usage. The boy took it as his duty to escort the girl to the hostel, take her to the canteen or to outside restaurants or just sit under the wisdom tree and talk endlessly. In general he won’t leave the girl alone not even for a moment so there won’t be a chance for anybody else. Even if it so happens that the girl is alone, no one will bother her as it is common knowledge that she has some one to care for her.
