Quick Transmigration: The Crybaby Is Swept Off His Feet by His Yandere Childhood Friend

A tearful, clingy crybaby who gets prickly at the drop of a hat × a cold, possessive big shot

After throwing a tantrum, Jiang Mumu is hit by a car and unexpectedly enters a quick transmigration world. System 81818 tells him that he can return to reality only after maxing out the protagonist's affection for him.

But... why does the protagonist's sworn enemy look so much like his childhood friend, who dotes on him endlessly?

And there's always someone hanging around his childhood friend, too blind to read the room, driving a wedge between them.

In the end, this leads to a misunderstanding between the two.

Heartbroken, Jiang Mumu decides to return to reality and sneaks over to the protagonist while his childhood friend isn't looking.

Then the System suddenly fixes a bug. It turns out his childhood friend was the target of the mission all along?
