Daughter's Target

Ze Ai Zima's heart was pounding more and more due to the sudden actions of Black Prince, she would have felt better if only the Black Prince had allowed her to look down or see the others.
However, the Black Prince forced him to look into his eyes, only his eyes.
That made Ze Ai Zima even sharper, and was forced to nod to speed up the discrimination process.
The Black Prince smiled smugly, this was his first smile after 499 years passed. The Red Prince was even surprised because of that smile, as if seeing an occult event.
Only Ze Ai Zima knows the meaning of that smile. The Black Prince smiled because he managed to silence Ze Ai Zima with Ze Ai Zima's own words.
