Childhood Friend or Boyfriend?

I Want to Read Shugo Chara!

Looking for books like "Heartcatch PreCure!: LOVE Magic Card Girl". The strongest, richest, most beautiful, and any pairing is fine (an all-pairing is fine too). The protagonist hides their true strength at first, then goes all out later. Preferably completed, with lots of feel-good wish fulfillment and a crowd of admirers.

I’m in a Reading Slump. Recommend Some Good Completed Novels!!!

A fast-paced plot with no dragging things out.
