Help me find this manhwa

I never read it and I wanted to right before everything disappeared :,)

I remember the summary was about how a villian got a gf(?) and was meeting her family but her family turned out to be heroes so he has to hide his identity from them. And the cover was a guy with dark grey hair and the background was pink(?) and he might’ve been smirking idkkk pls let me know if you find it …
