Lee Minho

Minho's past life had practically gone down the drain. It was terrible. On the day the academy's children had to choose their soul pets, he was given the weakest, Rank F Pengin. Jisung. That's what Minho named him. And the strongest pet was taken by Minho's envious classmate, Jeongyeon. She got an SSS-rank spirit snake, the rarest animal in the last 10,000 years.
Soon, after a couple of calm days, the Frost Apocalypse began. And so it happened that Jeongyeon's snake died instantly, as she couldn't stand the cold at all. And Minho, the penguin, instantly became the strongest, able to create a barrier against the cold, masterfully handled the blizzard, and became the most useful. But Jeongyeon acted cowardly, and soon she and her gang forcibly took the penguin. Jisung looked at him then, trying to escape, but this caused Minho's head to go to his head and he died.

But fate wasn't so cruel, as he had a chance to reincarnate on the very day of the spirit selection. Just as Minho was about to return to Jisung through his memories, Jeongyeon suddenly leaped forward, handing Minho her SSS snake and demanding he give her the penguin. It seemed Jeongyeon had reincarnated as well, and that wasn't a good thing. The smirk on her face clearly didn't bode well.
