plz help me find this

does anyone know the name of a bl that is a love triangle but the ml is obvious and so basically it started when they were teens in school i believe and the uke was from a noble family as well as the other ml and the main ml was believed to be from a poor family and the uke would tutor him and stuff and they fell in love BUT then in the future i think the ukes family got like in trouble and his dad and brothers got killed while him and his mom got separated as maids and both the ml try and find him and stuff
