Freaky Zeaky on the Sheets's activites

Characters: Brown hair (Uke), Dark colored hair (Seme)
Omegaverse, Manhwa

From what I remember, the brown haired guy has been having nightmares about him being treated badly by "some" guy. BTW Uke is an omega, but has no scent. Then his father dragged him into getting an arranged marriage with this rich guy (The seme). When the brown haired guy went to the meeting place, he was suddenly met with his favorite things, like his favorite flowers, and his fiance is really nice to him. Then the brown haired guy stayed at his fiancé's house, and he is still having those nightmares. Apparently it's a time travel manhwa (??). 

Thats all i can think of huhu (〜￣△￣)〜
