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.
