Long Time No See, My Sweet Girl

Looking for a Female Lead with a Tough, Rascally Attitude, Preferably a Soldier

I'm looking for books like "After Becoming a Young Vampire, She Was Forced to Take Up Arms".

The Leads Have Known Each Other Since Childhood, and After Returning Home, the Female Lead Transfers to the Male Lead’s School

Childhood sweethearts. The female lead is the male lead's idealized first love, and both leads come from prominent families.

Childhood Sweethearts, From School to Adulthood, Sweet Modern Romance

Fellow readers, I’m in a reading slump!

Campus Novels, Childhood Sweethearts, Family Friends, No Reborn or Transmigrate Stories

Youth, School Life

Looking for books similar to Vermilion Kiss. A high school romance where the leads fall for each other while they’re still in school. No fake sweethearts or scheming women, and both leads come from happy families. They’re both good at communicating, and their romance is passionate and youthful. They’re both like little suns.

Childhood Sweethearts, Well-Matched Families, Betrothed as Children, Good to Each Other, and Getting Married When They Grow Up

They're both smart and good-looking. The female lead is the campus goddess, and the male lead is the campus heartthrob. She's called him her husband since they were little, and he goes along with it. He also gets jealous easily.
