which BL?

I forgot to add this one BL Manhwa that is ongoing to my list I believe, it had the name twist in the title. It's about this dude who did not want to marry this one guy so he starts looking for men who are his ideal type he find this innocent looking blonde alpha and he tricks him into sleeping with him while the alpha is in his rut and then they get married bc of that and his goal is to get pregnant on the honey moon but the alpha kept pushing him away
