Reincarnated into a Dating-Sim sounds fun? But what if you have never heard about that “World of Myst” game? And that is exactly what happened to Sam Roland. Poor Sam with only basic-dating experience, had no idea he was supposed to “capture” the women he is hiding from.

When she reborn, she finally understood; men can never be relied on.
That being the case, she can only rely on herself to win, that
splendid brilliance she yearned for, in this lifetime.

To my scheming Stepmother and ruthless sister, I will
destroy all your backings, pull off your wings, and step on your
arrogance! As for Grandmother whom speaks kindly but has a snake-like heart,
and a father who is hypocritical and exploits advantages; I will tear
off your pretense and cut off your hope! Let’s see how you can still
scheme against me!

Witness her splendid fight against her stepmother, punish scum men,
and create havoc in the imperial court, as she soars with the wind and
rises above the water!

But as for that man who still stands! How dare he play with my heart?
