I didn't read a lot and I can't find it for the life of me. The MC transmigrated as some vicious wife whose husband "died" (actually still alive and hanging out on an island with his friends who I believe were soldiers). The MC decided to leave the big family but also goes back to help the younger brother? I remember a scene where the MC was spending money, or at least transferred the ML's money so the ML was trying to do something but found that he couldn't use any money. I hope to find this cause it's been bothering me for a few days and I felt like reading it recently. It was an MTL too.
