Lin Yi had a problem: he had a lovesick puppy disorder when it came to certain people.
No matter what they asked of him, he always had just three responses: "Sure," "No problem," and "I can do it."
He'd already spent himself into poverty trying to please them, and couldn't even afford next month's rent.
To cure himself, he had no choice but to complete the Lovesick Puppy System's missions, traveling through different parallel worlds to play the lovesick puppy.
[World One: Fulfill Target One's wish. Be his obedient, well-behaved lovesick puppy~]
Why is Target One the childhood friend he's already fallen out with?
[World Two: Fulfill Target Two's wish. Be his adorable, clingy lovesick puppy~]
Why is Target Two his icy boss?!
[World Three: Fulfill Target Three's wish. Be his devoted, never-leaving lovesick puppy~]
Why is Target Three the junior fanboy whose confession he turned down!!!
Lin Yi diligently plays the lovesick puppy until he's finally cured. He finishes his mission and retires to start a new life.
But he never imagined this would happen...
"I was too immature before. Now it's all over. I hope we can still be friends."
His hot-tempered childhood friend clenches his fists, his voice hoarse. "Have you fucking fallen for someone else again?! I've waited for you all these years. Would it kill you to like me just once?!"
His boss freezes for a moment, then shuts the door. "You seem to have underestimated me. I don't think you can just walk away from our relationship whenever you want."
The junior clings to him, voice trembling. "You can't leave, Brother! I'll do anything you ask if you'll just stay with me forever."
*One couple, main uke, both virgins.
*Split seme, (pseudo) reverse harem. All three men above are split versions of the seme, who eventually becomes one person again.
*The uke has no choice but to play the lovesick puppy, and he doesn't date anyone during the missions!
*The seme loves the uke throughout. At first, the uke chases him while the seme keeps up a composed facade and pretends to be reserved. In the middle, the uke stops chasing him, and the seme goes crazy but can't do anything about his darling, especially since one of his split selves is incredibly stubborn. Later, the seme falls apart and goes crazy while becoming the lovesick puppy himself.
