Cursed By The Snowstorm

Rachel Quinn died on the twentieth year after entering the Pocket Universe.
Twenty years ago, we both entered this story together.
Mission accomplished, I chose to leave, while she decided to stay in the Pocket Universe.
Until news of her death reached me.
Rachel left a final wish, hoping I would protect her daughter.
At last, after two decades apart, I returned to this world once more.
Rachel's former love interest remained the Wise Grand Master.
Prince Andrew, who once cradled my lifeless body, spitting blood in anguish, had now become the ruling sovereign.
How convenient.
Whether for reminiscing or revenge, I excel at both.
