Warning: The top only seems dominant (weak in bed); the bottom spoils him.
Call him aloof, gloomy, cold, warm on the outside and cold within, a crybaby, or a manipulative green tea, and I won't object. But calling him the top is going too far, isn't he obviously my baby?
World One: An aloof, affection-starved top student X a sunny, doted-on rich young bottom
Yan Han always thought he would get through three peaceful years of high school, go to university, find a job, work, and eventually die in peace. So when something calling itself an Anti-Stereotype System came looking for him, his first thought was to fast-forward straight to death. He thought about it, but in the end Yan Han still teamed up with the System. He didn't think anyone would like him, and failed to notice the intense possessiveness in the gaze of a certain scheming little ray of sunshine whenever it looked at him.
...N years later
"Don't kiss me." Yan Han was having trouble catching his breath from all the kissing.
"Baby, why are you so obedient?" Ming Zhe blinked, then kissed him again.
"You're so annoying." Yan Han lowered his lashes.
"You're so cute." Ming Zhe stared at him.
World Two: A gloomy, obsessive incubus top X a cool, carefree Immortal Venerable bottom
Fu Zhao was a deranged, obsessive top with a strong creepy-ghost vibe. He could have followed the usual formula, imprisoned the Immortal Venerable, and then gotten down to business. Unfortunately, he ran into Wenren Ying, an Immortal Realm Supreme whose name alone had kept the Three Realms in check for eight hundred years. Given that status, it made perfect sense that Fu Zhao later ended up imprisoned on Lingjian Peak, where Wenren Ying could do whatever he wanted with him.
"Wenren Ying, why don't you just die?"
"If I die, who will satisfy you?"
World Three: A warm on the outside, cold within, refined scoundrel of an actor X a gentle, elegant genius director
World Four: A mentally ill top who cries uncontrollably X a yandere, wealthy family powerbroker bottom
World Five: A formerly insecure, later disillusioned top X a formerly deranged, later devoted-dog bottom (bad ending)
(The order of these worlds may change.)
