Magic System in a Parallel World - Chapter 24: Tier 2 Magic Spell

The youngest princess of the country of Stellaus, Marietta, was betrothed in a political marriage to the General of the great militant country, Oltaire. General Belvant was often said to be strong, a fierce and terrifying god of a warrior. On the other hand, Marietta was a delicate flower of a princess. Everyone felt pity for poor Marietta’s situation, however, the truth was that Marietta found the General very dreamy… The story of a 30-year old General with a scary face (who was actually quite nice), and the tiny and adorable 18-year old Princess in their times of conflict and of lovey-doveyness.

She died in her prime as the Queen of Song.

After being reincarnated, she becomes a simple trainee.

Losing her former glory? It doesn’t matter—no one can compete with her voice as a beautiful singer.

Mocked by her lowly birth? It doesn’t matter—her true identity is enough to make the whole world tremble.

She owes huge debts? It doesn’t matter…

A powerful boss once whispered to her, “Your debt will disappear if you become my woman.”

But the proud her would reply, “I’m sorry. I would sell my art, but not myself.”
