The father-son relationship in this manhwa is healing me from all those fatherless/bad fathers/father favoring daughters while ignoring sons/cold and awkward relationship that's usually in manhwas. It's a rare thing to see loving dads of boys since we always see manhwa dads only showing affection to daughters
@yoongles boongles there really is barely any father-son manhwa like those father-daughter manhwa. When boys are the mc, they would usually go off on their own so it's not family story anymore. There is "How to Survive as a Dragon with Time-limit" though only for the first few chaps since they separated. It you're ok with found family, then "Trash of the Count's Family" if you haven't yet.
If you like manga then "Father and Son" which is a gag manga.
There's also a chinese novel as well that's similar to those father-daughter stories called: "The Whole Villain Family Can Read My Mind, and the Milk Ball Baby Become’s The Group Pet". But there is a bl element so if you're alergic to even the tiniest bits then not for you.
