Male Lead, Please Check Out Your Evil Girlfriend

Any Sweet Romance Novels Where the Characters Have Brains?

I recently read a mildly angsty quick transmigration story and can't get over it. I'd like to read something sweet to cheer me up. The angst came from various circumstances keeping the leads apart, even though they loved each other deeply. I want a story where they have to pursue each other, not one with mindless doting. School starts soon, and I don't want to lose my brain again.
