Ask for the name of a romance novel

The female lead's name has the character Jin. It's a school type. I was about seven or eight years old when I found it in my sister's room. I read it like a thief. I calculated that it should be published in the 80s or 90s. I really don't remember the plot at all. I just think it's very, very, very good ~~ but I secretly read it at that time, so I miss it very much.
Please answer the question a little more correctly, don't copy and paste a bunch of useless things, waste each other's time, you won't get any points, right?

Answer 1

But I don't have the information you mentioned.
