I'm happy to say that the title is Fall in Love with the Substitute (Yaoi)! After months of on-and-off searching, it was right under my nose the whole time. With the help of another person, I finally found it. I had passed by this manhua numerous times while looking for the chapters since it hadn't been updated yet, and I had only read those scenes in the novel. Thankfully, I had written some comments about the parents and brother, linking the novel chapter along with my thoughts in the comments of this manhua so I wouldn't forget. Since I last read it, 4–5 months ago, it has been updated and seems to have caught up, though I haven't read the new chapters yet to confirm. (No spoilers, but I checked the last chapter and it did seem that the brother at least found out and is groveling).

It’s also a BL where the Uke is mistreated by the Seme. However, he was separated from his family and his family always thought that he died as a child, but he was actually kidnapped by a servant. His family consists of his mother, father, and an older brother who always blamed himself his younger death. They actually meet him at the seme’s party, unaware that this is their biological brother/son and feel pity for him when he is humiliated by the seme’s friends. I can’t seem to remember what happens next
