A tough request, there aren't too many of those (￣∇￣")
Well try these, but sadly in most father-son relationship don't play main role.
https://www.mangago.me/read-manga/the_count_s_intruders/ - It has angsty beginning, but later it gets better
https://www.mangago.me/read-manga/i_became_the_hero_s_mom/ - in this one romance is more important than father-son relationship tho
https://www.mangago.me/read-manga/i_found_a_husband_when_i_picked_up_the_male_lead/ - It's uncle-nephew duo here, but he raises him with FL
https://www.mangago.me/read-manga/how_to_hide_the_emperor_s_child/ - It's good, but slow burn, you wil read like 50 chapters before you will get nice son-father relationship, cause FL hides child from ML
https://www.mangago.me/read-manga/i_gave_birth_to_a_murderer_s_child/ - it has not best drawing style and is honestly boring
https://www.mangago.me/read-manga/when_i_quit_being_mother_in_law_everyone_become_obsessed_with_me/ - and once again romance is more important than father-son duo
