I forgot what it is, but the MC and ML are blonde and black haired. i remember that the Mc's blond father is a bodyguard/agent/someone that uses guns in a tuxedo, but hes out of service now because he got sick, hes bald and in a wheelchair. And that the son is working hard to earn money.

All i remember is seeing a photoframe of him being so handsome when he wasnt sick and i want to see him again. I remember that the dark haired ML values him too as a father figure but he lives a life of crime(or similar) and he also carries guilt for fcking his son.

But he cares so much about the MC's father.. its a popular manhwa too

Its a fully colored webtoon
It has the style of ancient chinese setting
The female lead is a child with green hair who was a princess from a fallen nobility
And the male lead is a strong prince with white hair.
The male lead takes her and took care of her like his daughter, the prince has many brothers, once of which is a doctor who is being pursued by a handsome tanned rogue, and another is an androgynous pale violet haired wizard(?) That loves money and will extort you.

Ive read this so long ago and i was hoping i can find it fast cuz theres not much greenhaired female MCs. But i cant find it QAQ the only notable scene i remember from it was the moneylover brother disguised as a belly dancer to enter a girl worship group and thats ALL
