Oh my lord, you're a life savior. That was killing me.
It wasn't, but I haven't read this one and it looks interesting so I'll check it out. ty!
Okay so there's a significant age gap and I think there's somewhat of a sugar daddy sort of relationship going on, or the older guy was at least very rich. For some reason I have memories of the younger guys sister being involved in the story at some point, but I could be getting confused? I dunno. It had a more sketchy style. The line art wasn't super clean. That's literally all I can remember, but I really liked it and wanted to read it again.
