After I Accidentally Sent My Confession to My Crush Instead of My Senior

Looking for Short, Brain-Off Feel-Good Stories

Looking for Completed Novels Where the Heroine Takes Advantage of the Hero After His Breakup

I can't get into quick transmigration or anything like that. I just want a novel where the female lead has had a crush on the male lead for years, then takes advantage of his breakup to make her move. I haven't read this kind of story before; the ones I usually read have the male lead taking advantage of the female lead's vulnerability. I want one where the female lead does that instead.
