I'm desperate...

So it's a bl I've read before but I don't remember the title. I tried to find in my read, reading, and want to read lists...but it's not like I remember the cover or name so I didn't find it. What I remember is a part from that manga. So these two people are in a relationship by that time but things were not exactly smooth sailing. To add to that, the uke found out that his father, who was a proffessor in this university, most likely music, had a relationship with the seme's brother who killed himself. Their relationship got exposed by the brother's bestfriend and things did not go well. The uke felt guilty and tried to break off their relationship but the seme stopped him. The bestfriend owned a bar with a music studio underneath I think? He got dark hair and glasses I think? The uke is most likely blond and so is the father...I can't remember for the seme.
This description is kinda complicated and all I know. But if you remembered anything familiar, please let me know. I'd be forever grateful.
