[One-on-one romance, both leads are chaste] Black-hearted, lovesick, obsessive loyal puppy X refined, elegant, proud misanthrope
Dong Jie is refined and aloof, indifferent to everything and content to live out a quiet, uneventful life.
But an unexpected incident at a bar disrupts his peaceful routine.
Qu Jingzhe, his little fanboy whom he hadn't seen in years, has grown into a dazzling young man. After the bar incident, a twist of fate makes him Dong Jie's tenant.
Dong Jie tries everything to drive him away but fails, so he lays down one strict house rule after another. Qu Jingzhe, however, is always testing his limits.
Whenever Dong Jie turns cold and heartless, Qu Jingzhe immediately opens his innocent, wide eyes and pretends to droop his ears and tail.
Knowing Dong Jie responds to softness, not force, Qu Jingzhe quietly makes his way into Dong Jie's territory, warming his long-frozen heart with his passionate devotion until he finally brands Dong Jie as his own.
“Little Dong, you were the one who flirted with me first. How can you expect me to let you go?”
“How did I ever let those puppy-dog eyes fool me? He's a wolf in dog's clothing!”
P.S. His obsession leads to unconventional behavior. If that's not your thing, please move along.
