So 6 modules of KVLS, followed by 4 modules of KVLS2 behind the bridge and 15 ballistic missile cells behind it. Seems like they are planning to arm it with two different types (one heavy and one light) of ballistic missiles. Maybe the KVLS2 is meant for the supersonic cruise missile but I don't think that it would be so large that it wouldn't fit KVLS, though there ain't much info regarding such, so we'll see.
I think KVLS-II is in 4-round modules, so technically 8 modules, but still 32 missiles either way.
I think it's even more of a kitchen sink than that. There are two 2-missile launcher frames that appear to fold down between the superstructure and flight deck (we see one pivoted to vertical and one stowed horizontally) and an even longer/larger missile in a framework hanging over the transom. I can't find sources for what those missiles might be, though. I think they're considerably longer/larger than anything publicly disclosed from the RoK.
