I don't read the novel. But, for the shaman thing, it really downs to calling. I think it's in so many culture with differentiation, but as far as I know, in Korea, when people born with imbalance energy, they either became weak or strong spiritually. And they need something to balance the energy.
And sometimes when the spirituality is so imbalance that the body can't handle, they need help from god and became a medium/shamans, or share/receive the energy with/from other people.
Ooooor, at least that's what I've learn from so many horror story from k-variety show.
If it's variety, it's a common way to promote in korea, usually these type of manhwa used some already popular format of variety in korea, maybe they used that too. Like seasonal variety in tvN.
I usually prefer watching variety to drama, so I'm more familiar with it.
I don't think they're gonna made him like an idol tho, it doesn't fit his image.
I don't think he'll really go into singing... but more so he can develop his voice? Like... think Morgan Freeman... he's an established actor, but there's many audiobooks and documentaries narrated by him right? And many animated characters (specially in movies) are voiced by actual actors instead of voice actors... Having a good voice and pronunciation is actually very important for actors. Especially transmitting emotions through it. And the best way for him to get talent in it is through a singer... so... I guess that's why... but the gig... wasn't it a radio interview? Did I miss something?
I haven't finished the novel. But from what I see, he is supposed to be a TOP STAR, not only an actor. Even the title, both in Korean and in English is a "Top Star" or superstar. Which mean he will likely do all short of things, including singing. Because the more he become popular, the more lifespan he can harvest. You know, because these days not a lot of people enjoyed watching drama or movie, some only interested in music, so he probably tried to widen his reach to harvest as much as lifespan he can. He is desperate lmao. If you remember, his lifespan that was showed in the system when he wake up after the car incident was in negative, around -28k, and the lifespan he can harvest by helping people individually was only in tens (20-50 days or something), but recently he figured out by became popular he can gain up to hundreds days
I'm starting to feel it boring as I find myself skimming through it instead of reading dialogues. What's wrong with me i really want to enjoy and read it. ʕಠ_ಠʔ
