I read one manhua long time ago and now I can’t find it anymore. Seme is prince and uke is duke(something like that). It’s about two childhood friends and if I’m not wrong, they promised each other to marry when they got older. But something happened and then seme had to go for war and uke was kept waiting for him. Uke became duke(? I’m not sure) and when seme came back from war, he brought one pretty guy and he said that one is his lover. Uke was heartbroken but he still tried to keep himself. But later the emperor (seme’s father) forced them to marry. Seme wanted to refuse but can’t so he tried to negotiate with uke. But uke also have some difficulties so he just accepted the proposal with the emperor.

And I don’t remember anymore and I can’t find it. Anyone please let me know if you happen to know this manhua. Thank you and sorry for my bad explanation.
