My Wife Passed Away, and After Being Reborn, I Became a Devoted Husband

Sweet from start to finish. Insulin recommended while reading.

After being reborn, Jiang Fan returns to his senior year of high school. At this point, his future wife is still an unnoticed nobody in class.

He sets himself three goals.

Look after Bai Xiaoyu.

Protect Bai Xiaoyu.

Cherish Bai Xiaoyu.

When Bai Xiaoyu is falsely accused of cheating, Jiang Fan hands in a blank exam paper and walks out of the classroom, holding an umbrella over her.

"Feeling better?"

After spending some time together, Bai Xiaoyu is touched and decides to start changing for Jiang Fan:

Grow her hair long, put on some weight, become more outgoing...

She resolves to stop being an insecure and timid person.

Ten years later...

"Honey, you're awake?!"

Bai Xiaoyu smiles sweetly and throws her arms around Jiang Fan.
