The Cannon Fodder Rebound, Trapped in a Love Triangle [Quick Transmigration]

In every world, there's a cannon-fodder gong who ends up taking over someone else's mess:

They're unremarkable and mediocre, loving the protagonist shou with pitiful devotion.

When the protagonist shou is dumped by a scum gong, he drops out of school to earn money and support him;

When the protagonist shou lacks talent, he risks destroying his spiritual roots to find a rare treasure that can restore them...

They give everything for the protagonist shou.

But the ambitious protagonist shou finds them dull and boring, and joins forces with the protagonist gong to cheat on them.

The cuckolds end up seething with resentment and all go on strike, disrupting the worlds' operations.

The gong is bound to the Cuckold Comeback System and sent to various small worlds to play the cuckold and keep the plot on track.

But...

Weren't these supposed to be cannon-fodder cuckolds? Why are all the protagonist shou's love-triangle dramas following him around?
