[Quick Transmigration] The Protagonist’s Scumbag Ex-Boyfriend

What does an ex-boyfriend mean in a novel? He's nothing but cannon fodder, destined to be miserably face-slapped by the protagonist and his true love. And Xie Zhining has transmigrated into the role of the protagonist's scumbag ex-boyfriend...

In his first life, he mistreated an aloof, desireless Immortal Venerable who was also his master. When he transmigrated into the story, the two had just fallen out...

In his second life, he mistreated a wealthy CEO. When he transmigrated into the story, the scum of a lover was about to cheat, and the CEO was on his way to catch him in the act...

In his third life, he mistreated an emperor. When he transmigrated into the story, the top scholar had just married his bride on their wedding night, while the emperor brooded in secret...

Xie Zhining was desperate. Male lead, can't we talk this out? Give me a chance to get back together with you?

I keep transmigrating as a scumbag ex-boyfriend. What am I supposed to do? I'm panicking too! But it's fine. Even in a panic, I remain impeccably calm. I'm not afraid of being cannon fodder ex-boyfriend (not really).

[One-on-one romance. All the male love interests are the same person. Sweet, mutually doting romance.]
