Maybe not once!

Maybe hundreds of times.

If you sign in once a week, it will be four times a month.

A semester lasts four and a half months, and a year is nine months. 36 times.

Two years is 72 times. The holiday factor is not included here. Exclude more than once a week. So, with holidays and so on, it's a hundred times.

But in high school, the pressure of study is great, and the beginning of love will not go that far. It may not have happened.

Maybe it happened 1-2 times in college.
