Ok so my memories of it are blurry asf so stay eith me. First of i think the setting was like royalty u know prince and princesses ITS YAOI THO SO DONT THINK ITS PRINCESS X PRINCE and the mc gets pregnant if im not wrong its omegaverse? But he cant remember who the baby daddy is lol cause he was eventually drugged or heat indueced all he remmebers is the man he slept with had pinkish or redishh hair so hes like naw fam i gota leave asap. Then i think the ml was like a prince or king? And he was mc best friend or something but hes like why is mc avoiding me and he gets mad when he finds out mc is preganant and i thinkmc told him that he isnt the father cause mls hair is black or somthing. And spoiler ml was the daddy but he also (ml) didnt remmeber cause he was drugged or in rut and he find out when mc was kidnapped and some other dude who was also inlove with mc told ml. If im not wrong that dude who was also inlove with mc was the one who planned on drugging nc to gulp..try and rape him;( . I know its all wonky but if someone can make sense of it pls help.
