Don't Be Scared, Little Villain: I'll Use My System to Stack the Deck for You

[Quick transmigration + two male leads + 1v1 + both leads are virgins + fast-paced + sweet romance + a little angst with lots of sweetness + humiliating scum] Huo Zhiyi is a fine young man of the twenty-fourth century: he doesn't smoke, drink, or gamble, and in his spare time he likes to play match-three games and Plants vs. Zombies. But then a falling object from above cuts short his wonderful life. Luckily, Heaven takes pity on him and gives him a chance to come back to life.

The only problem is that filling up his resurrection progress bar is hard. He has to travel between various worlds on the verge of collapse and complete missions, reforming great villains who might one day destroy the world.

Before meeting the villain, Huo Zhiyi is a little nervous. But when he sees the poor, pitiful little guy, all he feels is heartache.

He meant to raise him as a little brother, but somehow, along the way, the kid became his wifey. Oh my, he's irresistible!

In short: How is this guy a villain? He's obviously my precious treasure!
