Quick Transmigration: A Crazy Villain? The Host Is Totally Into Him!

[Two male leads, main POV is the bottom, cheerful and goofy bottom]

[The top is the same person throughout; happy ending]

A help request from System 718:

This is so annoying! So annoying! <(`^´)>

My Host was working diligently on missions, and suddenly turned into a lovesick idiot. What do I do?

Waiting for answers, and I’m kind of desperate ψ(`∇´)ψ

World One: Modern setting

Timid, introverted college student × smiling crime boss who has influence in both the underworld and the legitimate world

The start of System 718’s miserable career: its star employee instantly becomes a lovesick idiot.

World Two: Fictional interstellar ABO setting

Sweet and gentle homemaker omega × cold-faced but warm-hearted, powerful colonel alpha

Cold and ruthless?? Workaholic?? The legendary colonel is supposedly frigid?? (Fictional interstellar setting, no politics.)

Married first, in love later √

World Three: College romance (all main characters are adults)

Broke, spoiled young master × dirt-poor, deaf, top student and loyal puppy who’ll work hard to support his wife

Once a young master who ruled the campus, he loses everything overnight and ends up homeless. He can only tug at the sleeve of the poor top student he used to look down on, begging to be taken in.

World Four: Fictional historical setting

A beautiful princess sent by an enemy nation as a political bride (a man in disguise) × ruthless emperor top

Other worlds to be decided…
