Yupp they were and I love Park Hanhoo's Manager :)
Do u remmeber what chapter?
idk but mateo is like a "main" side character there, and is part of the ML's Arms dealer company.
For lucifer though, i forgot what chapter but mateo once asked for his help (I only remembered Lucifer was there cuz i took a ss cuz u kno hes attractive)
Ithink I saw some peeps from author's other work "Park Hanhoo's manager"? Idk it's been so long. But I'm pretty sure Lucifer and Mateo were there
