Maybe you can try, some of this novel:
1. Those Years in Quest of Honor Mine (have manhua).
The MC & ML, not married (yet) but everyone know that MC is the soulmate of ML, even the emperor know (he can't even persue the ML to married another girl). BTW, when I say everyone, its literally every person in that kingdom (there even some fanfic/novel about MC & ML).
2. My Husband is Suffering from a Terminal Illness (no manhua).
The MC & ML already married (by contract) but they will fall in love eventually (cliche I know) but in this novel, the ML is the cutest tsundere that I have ever read & the MC work extra hard to make the ML open up his heart (even he know that he love MC & MC know about it but he still doesn't want to tell him) & every little romantic action that ML do always with a reason, like he want to hold MC hand, he will say "why you become thin?" or when he want to kiss MC, he will wait until MC sleped. its so funny & MC is a badass, he doesn't need ML to protect him, MC can handle his own problem.
3. Reborn with an Old Enemy on the Day of our Marriage (no manhua as long as I remember). The MC & ML almost getting married but they died in plane crash when they on the way to another country to get married. Then both of them get rebirth when they still a high school student. They were enemy and rival when they were students, then imagine when they suddenly getting along+feed dog food everyday, yeah all the people that know their rivalry become so confuse. its interesting story & so funny, they tried to fix all the thing that go wrong in the first place, its like a second chance in their mess up life.

Can you guys please suggest me something similar to this one and 'stop bothering me emperor' (which I came to know was getting a manhua).....that is where uke and seme are power couples and married/committed from the beginning. Preferably in colour?
