Krista is a Christian girl who is just starting 9th grade in a new school. She wants to show others the love of Christ, but she quickly learns it's not quite as simple as it seems.
In other words, wearing a cross doesn't make you a Christian.
The title of the comic is based on Philippians 1:6 - "For I am confident of this very thing, that He who began a good work in you will perfect it until the day of Christ Jesus."
This is a shojo-style comic (in my opinion) with some romance, drama, and comedy. It reads from left to right.
