The protagonist was sold as a slave in the market of Ryan City. In desperation, he was bought by a woman named Serafina Silvermoon. She looks as gentle as moonlight, but she is burdened with a cursed bloodline and a heavy fate. Under her guidance, the protagonist discovers that he possesses the rare talent of "starry sky magic" - the ability to use the power of stars as a medium to cast dual magic of ice and fire.
From the forbidden book pavilion of Silver Moon Monastery to the frost and fire storm on the imperial battlefield, the protagonist grows from an ignorant time traveler to the leader of the Fire Resistance Army. Not only did he learn to look up at the stars and control the starlight, but in the turbulent era, he and Seraphina established a deep relationship that began with dependence and finally stood side by side - from her shielding him from the hidden arrow, to the first kiss in the ruins, to the white-headed promise under the starry sky.
However, the road to resistance is far more cruel than imagined. The Imperial Holy See secretly controls everything. Serafina's ethnic origin is regarded as heresy, and she herself is involved in an ancient conspiracy about the "collapse of the Kingdom of God." When the sky cracks and the devil descends, she chooses to sacrifice herself in exchange for a glimmer of life; and the protagonist must find the only way to save her and the world between the stars and the fire.
Purpose: This is a story about time travel, growth, resistance and affection - when the stars fall, mortals can also light up the sky.
