ngl 3 of these questions could be answered if you re-read the manhwa and the others are stuff that will be answered eventually unless you can't wait and look for novel spoilers
except the mc and youngest member Q, there's nothing unique with him vs the other members, he's just like that lol
I think it's rushed considering that we are already in season 4 but noting happened
What happened to the real sihyeon?
What is the connection between the MC and
the ML in the drama?
Who is the male lead ?
And what is the relationship between the MC and the youngest member of their group?
Cause there's no flashback of their interaction
And why are they against to MC remembering sihyeon's memories?
And who is the mysterious Sponsor?
