Reborn: After the Sweet, Gentle Substitute Quits, the Scumbag Turns into a Devoted Dog

One-line summary: Whoever wants to be the substitute can do it! I'm done!

1v1, both leads devoted to each other, both reborn, a whole pot of melodrama!

The gong was calculating, stubborn, and too proud to admit his feelings in his past life. Reborn, he becomes a loyal puppy, obsessively pursuing his beloved and shamelessly flirting.

The shou was pathetic and self-effacing, willingly playing the substitute in his past life. Reborn, he's heartbroken, but finds himself unable to escape.

In their past life:

Li Siyan had a white moonlight he loved but could never have. She died.

Yu Yang loved Li Siyan so much he couldn't help himself, and willingly served as his substitute for thirteen years.

As he lay dying in a car accident, all he wanted was a little tenderness for himself.

Yet decades of devotion and companionship couldn't win even a moment of affection from Li Siyan. Damn it, the man didn't even bother pretending!

In this life:

Yu Yang returns to ten years ago. My youth at thirty-six, wasted just like that! If I ever play the substitute again, I'm a dog!

Just as Yu Yang is trying to bring the dog of a man and his white moonlight together...

Li Siyan's eyes redden with anger as he protests miserably, “You scumbag! I'm carrying your baby, and you're just going to abandon me like this?”

Yu Yang: Holy crap! What is this dog of a man babbling about in front of his white moonlight?!

The white moonlight's face turns pale, then green, before she turns and walks away.

Yu Yang sighs in frustration. “Your wife is leaving! If you don't chase her now, you'll lose her!”

Li Siyan grins foolishly. “Then you run away. I'll chase you.”

Yu Yang: Are you insane????
