His sweet and gentle fiancée turned out to be a fellow transmigrator. This world was based on a danmei novel she'd read before transmigrating, and Jiang Jingzhi was the protagonist gong.
"So this is a danmei novel?"
"Yes."
"Then who are you?"
"I'm your sister-in-law."
"Oh."
An aloof-seeming male Alpha protagonist who can't stop grumbling internally and just wants to laze around x a gentle-seeming female Omega protagonist who always has a little play going on in her head.
Theme: Don't give up and slack off!!
