thanks for all your help guys but ive actually found it!!! its this https://www.mangago.me/read-manga/the_prince_and_his_mischievous_one/.
I forgot this even existed
me too tbh it randomly popped in my head out of nowhere and i HAD to find it to make sure i wasn’t going crazy and creating stories in my mind i rememeber it being an ok kinda cringy read, but the comments are making it seem so bad i wanted to reread but now im put offff
im pretty sure it was a (chinese?) bl manhua and the mc was blonde and a prince. the ml was this black haired guy and he killed the mc in the future. The mc regressed and stuff happened. This is such a bad explanation but u cant remember it to save my life
