something with intense sexual tension, but its not rushed in the first few chapels please

you have better luck with manga when it comes to this, with manhwas it's a lottery if there's no ducking in the first 5 chapters, my reco would be How my daddies became mates, they only did it like at the near end, also my darling liar. For manhwa, there's A painter behind the curtain- has great sexual tension and angst but in b/w, so if you prefer color, skip; Incorrigible is also good and the cp only did it in the end but it's a short one
