Congrats on the speaking line, Ahjuushi
That said unless ur chasing that dream for a decade and that dedicated/in love with acting enough to be satisfied with just being on set, and understandably you can’t “easily” get a starring role like most MCs, I don’t think it’d be “worth it” for some bg chara or like one line unless you’d only have to show up for like an hour and spend the rest of ur day at a diff job unless ur retired or have a really well off supportive family/partner
If not doing other odd jobs on the set like manual labor too
